Drill a 1/4" hole in the desired location and mount the switch by passing it through the panel from the
underside. Secure the switch using the nut, star washer, and on/off face plate. It is suggested that the
switch be oriented to allow the on position to be up toward the driver and the off position to be down or away
from the driver. Route the switch wires toward the control module.
The APS-685 is to be used in vehicles with AUTOMATIC TRANSMISSIONS only! Although this combina-
tion Keyless Entry/Remote Start unit is a sophisticated system with many advanced features, IT MUST
NOT be installed into a vehicle with a manually operated transmission. Doing so may result in serious
personal injury and property damage.
IMPORTANT!
DO NOT PLUG THE SIX PIN MAIN POWER HARNESS OR THE MULTI PIN INPUT / OUTPUT HARNESS
INTO THE CONTROL MODULE UNTIL ALL CONNECTIONS TO THE VEHICLE HAVE BEEN MADE.
AFTER SELECTING YOUR TARGET WIRES AS DEFINED BELOW, DISCONNECT THE NEGATIVE
BATTERY CABLE FROM THE VEHICLE BATTERY PRIOR TO MAKING ANY CONNECTIONS.
WIRING THE 6 PIN MAIN POWER HARNESS:
RED w/ WHITE Trace Wire: + 12 volt Battery 1 Source
Connect this wire to a + 12 VDC constant source found at the vehicle's ignition switch using the 30 Amp
fuse and holder provided. This wire provides power for the control circuit as well as the ignition 1 and
ignition 2 relays.
RED Wire: + 12 Volt Battery 2 Source
Connect this wire to a + 12 VDC constant source found at the vehicle's ignition switch using the 30 Amp
fuse and holder provided, but NOT the same vehicle wire as used by the battery 1 source. Most vehicles
have more than one battery source supplying power to the ignition switch. Separate feed wires must be
used for the Red and Red/White wires. If your vehicle does not have two battery feed wires at the ignition
switch then it is possible to connect both wires to the vehicle's battery. This wire provides power for the start
relay and the accessory relay.
IMPORTANT!
It is the responsibility of the installing technician to determine the load factor of the vehicles electrical
circuits when the vehicle is running and to adequately fuse the two power wires based on that load. If the
vehicle, running under load with the air conditioned, heater blower motor, and accessories exceeds 24
Amps continuous, we recommend that two fuses be used in combination on each power wire as shown
below. For additional information see Tech Update issued 9/30/96.
YELLOW Wire: Starter Output
Careful consideration for the connection of this wire must be made to prevent the vehicle from
starting while in gear. Understanding the difference between a mechanical and an electrical Neutral
Start Switch will allow you to properly identify the circuit and select the correct installation method.
In addition you will realize why the connection of the safety wire is required for all mechanical
switch configurations.
Failure to make this connection properly can result in personal injury and property damage.
In all installations it is the responsibility of the installing technician to test the remote start unit and assure
that the vehicle cannot start via RF control in any gear selection other than park or neutral.
In both mechanical and electrical neutral start switch configurations, the connection of the Yellow wire will
be made to the low current start solenoid wire of the ignition switch harness. This wire will have +12 volts
when the ignition switch is turned to the start (crank) position only. This wire will have 0 volts in all other
ignition switch positions.

NOTE: This wire must be connected to the vehicle side of the starter cut relay (if present). For the
electrical neutral switch configuration, this connection must be made between the starter inhibit
relay, (if present) and the neutral safety switch as shown in the following diagram.
Failure to connect this wire to the ignition switch side of the of the neutral safety switch can result in
personal injury and property damage.
SEE NEUTRAL START SAFETY TEST FOR FURTHER DETAILS.
(if present)
BLUE Wire: Ignition 1 Output
Connect this wire to the ignition 1 wire from the ignition switch. This wire will show +12 volts when the ignition key is
turned to the "ON" or "RUN" and the "START" or CRANK" positions, and will have 0 volts when the key is turned to the
"OFF" and "ACCESSORY" positions.
For Diesel Applications, this wire must be connected to the ignition circuit that powers the glow plugs if the vehicle
requires glow plug pre-heating. (See selectable feature #9)
GREEN Wire: Ignition 2 Output
Connect this wire to the ignition 2 wire from the ignition switch. This wire will show + 12 volts when the ignition key is
turned to the "ON" or "RUN" position and is some cases the "START" or CRANK" position. This wire will show 0 volts
when the key is turned to the "OFF" and "ACCESSORY" positions.
NOTE: See programming information concerning this wire to allow output during the "START" mode.
VIOLET Wire: Accessory Output
Connect this wire to the Accessory wire from the ignition switch. This wire will show + 12 volts when the ignition switch
is turned to the "ACCESSORY" or "ON" and "RUN" positions, and will show 0 volts when the key is turned to the
"OFF" and "START" or "CRANK" positions.

WIRING CONNECTIONS: 12 Pin Input / Output Harness
Black Wire: Chassis Ground Source
Connect the Black wire to a known vehicle ground source or to a solid clean metal part of the chassis. Be certain to
remove any paint or grease and secure this wire with a self taping screw and ring terminal.
BLACK w/WHITE Tracer Wire: Control Switch
The Black w/ White tracer wire provides ON-OFF control of the Remote Starter.
When the Black w/ White wire is switched to a full time ground, the Remote Start Module is operative. When the Black
w/ White wire is at open circuit through the control switch, the remote starter is disabled.
Connect the Black w/ White tracer wire to one of the wires from the back of the previously mounted control switch.
Connect the remaining wire of the control switch to chassis ground. Always try to mount the switch so that the ON
position is in an upward or toward the driver direction.
GREY Wire: Negative Inhibit Input 1
Connect the GREY wire to the previously mounted hood pin switch provided . This wire will be routed through the fire
wall into the engine compartment. It is necessary to use an existing grommet when passing wires through the fire wall
to prevent short circuiting. This is an important safety feature and failure to use this feature can result in serious injury.
Route the wire to the pin switch and connect it using the bullet connector provided.
GREY w/ BLACK Tracer Wire: Negative Inhibit Input 2
Any time the grey w/ black tracer wire is grounded, the Remote Starter will stop operating, even if the signal is received
from the transmitter.
If the brake light switch in the vehicle switches ground to the brake light circuit, connect the Grey w/ Black trace wire
to the output of the brake light switch. If the brake light switch in the vehicle switches +12 Volts, do not use the Grey
w/ Black wire; see Brown w/ Black tracer wire.
BROWN Wire: Positive Inhibit Input 1
Any time + 12 Volts is applied to the Brown wire, the Remote Starter will stop operating, even if the signal is received
from the transmitter.
If the vehicle has a factory installed hood pin switch, and that switch provides + 12 Volts to an under hood light, the
Brown wire can be connected to the existing pin switch.
5
BROWN w/ BLACK Tracer Wire: Positive Inhibit Input 2
Any time + 12 Volts is applied to the Brown w/ Black tracer wire, the Remote Starter will stop operating, even
if the signal is received from the transmitter. If the brake light switch in the vehicle switches + 12 Volts to the
brake light circuit, connect the Brown w/ Black trace wire to the output of the brake light switch. If the brake
lightswitchinthevehicleswitchesground, donotusetheBrownw/Blackwire;seeGreyw/Blacktracerwire.
Brake Switch Positive Shutdown Detail
YELLOW w/ BLACK Tracer Wire: + 12 Volt Alarm By - Pass Output
NOTE: YOU MUST DISCONNECT THE IGNITION INPUT OF THE ALARM FROM ANY OTHER
WIRE THAT IT IS PRESENTLY CONNECTED TO IN THE VEHICLE.
This wire provides a + 12 Volt output when the ignition key is turned to the “ON” position, and 0 Volts when
the ignition key is “OFF” and when the vehicle is running under the control of the remote starter.
This wire should be connected to the ignition input of the alarm system.
The Yellow w/ Black wire output will allow you to remote start the vehicle while leaving the alarm armed, and
to lock/unlock the doors while running under control of the remote start unit.
(2) WHITE Wires: Parking Light Flasher
These wires are the COMMON and NORMALLY OPEN contacts of the on-board parking lamp relay.
If the vehicle's parking lights are a +12 volt switched system, connect (1) of the White wires to a fused (15A
max.) +12 volt battery source, and connect the second White wire to the vehicle's parking light wire.
If the vehicle's parking lights are a chassis ground switched system, connect (1) of the White wires to a
chassis ground source, and connect the second White wire to the vehicle's parking light wire.
6
LIGHT BLUE Wire: Ignition 3 / Shock Disable Output
This wire provides a 300mA ground output that becomes active 3 seconds before the Remote Start Unit
initializes, and remains grounded while running plus an additional 4 seconds after the Remote Start Unit
turns off. In all of the applications described below, a relay will be required.
The Light Blue wire can be used to accommodate the following situations:
A. Shock Sensor By Pass:
If there is Shock Sensor used with an alarm system and it is not shunted during the Remote Start
activation period, then vibration from the running vehicle can cause the alarm to trigger. In this case,
connect the Light Blue Wire to terminal #86 of a external relay. Connect terminal# 85 of the relay to a
fused + 12 volt battery source. Cut the shock sensor trigger wire and connect one end of the cut wire
to terminal #30 and the other end of the cut wire to terminal #87a. Just before the Remote Start unit
is activated, the relay contacts will open, preventing the shock sensor's operation until the Remote
Start unit shuts off.
B. Ignition 3 Output:
Some newer vehicles use a third ignition wire which is required to start and keep the vehicle's engine
running. If this is the case, connect the Light Blue wire to terminal #86 of an external relay. Connect
terminal # 30 & # 85 to a fused + 12 volt battery source rated for a minimum of 25 Amp. Connect
terminal # 87 to the third ignition wire in the vehicle.
C. GM VATS Key Override:
If the vehicle has the General Motors VATS system installed, you will need to by-pass the system
while the vehicle is operating under the control of the Remote Start Unit. To Do This;
1. Measure the resistance of the resistor pellet on the ignition key then select a resistor within 5% of
the key's value from the resistor pack supplied.
2. Locate the pair of VATS wires in the vehicle, usually a pair of thin gauge wires running from the
ignition switch to the VATS control module.
NOTE: These wires are typically White w/ Black trace and Violet w/ Yellow trace, however in later model
Cadillacs, they are run through an orange sleeve, and are either both Black, both Yellow, or both
White wires. Consult the factory service manual for additional information.
3. Connect the Light Blue Wire from the Remote Start Unit to terminal #86 of an external relay. Con-
nect terminal #85 of the relay to a fused + 12 volt battery source.
4. Cut (#1) wire (as shown), and connect the ignition switch side of the cut wire to terminal #87a of the
relay. Connect the other side of the (#1) wire to terminal #30.
5. Connect the previously selected resistor from terminal #87 to the second (#2) wire (as shown).
NOTE: The above information and following diagram is for the GM VATS system only. For GM PASS
LOCK System you will require the Audiovox AS-PASS II Module.

General Motors VATS By-Pass Diagram
DARK GREEN/ORANGE Wire: Tach Sensor Input
This wire will continually monitor the engine tach rate while the unit is under power of the Remote Start
module. This wire will be routed to the vehicle ECM tach input or through the firewall into the engine
compartment and connect to the negative side of the ignition coil. This Remote Start unit learns the tach
rate of the vehicle and in most cases will operate properly from one multi coil pack regardless of the number
of cylinders. If the vehicle has a single coil unit for each cylinder, it may be necessary to connect this wire to
more than one cylinder for proper tach reference. See multi coil wiring detail shown later in this manual for
additional information.
3 Pin Door Lock/Unlock Harness: (White Connector)
The Red & Green, Door Lock/Unlock output wires provide either a pulsed ground or pulsed + 12 volts to
control the vehicle door lock / unlock circuits. The Red/Black 2nd Unlock output wire provides only a
pulsed ground, and when used, must be wired as shown later on in this manual. The output of these wires
has a maximum switching capability of 300mA. Many vehicles today have factory door lock relays which
can be connected directly to these outputs. However, always confirm that the factory relays in your par-
ticular vehicle do not exceed the rated 300mA output of the units door lock/unlock/unlock 2 circuits. Plug
the three pin connector of the door lock/unlock harness into the mating connector shell of the control
module. Determine the door lock circuit of the vehicle you are working on and wire according to the
diagrams shown.
3 Wire Ground Switched Door Lock Circuits:
In this application, the Red wire of the door lock harness provides a ground pulse during locking or pulsed
ground lock output. Connect the Red wire to the low current ground signal wire from the factory door lock
switch to the factory door lock relay.
The Green wire of the door lock harness provides a ground pulse during the unlocking sequence, or
pulsed ground unlock output. Connect the Green wire to the low current ground signal wire from the
8
factory door unlock switch to the factory door unlock relay. See Below For Wiring Detail.
3 Wire Ground Switched Door Lock/Unlock Wiring Detail
3 Wire Ground Switched 2 Step Door Locks
In this application, the red wire provides a ground pulse during locking, or the pulsed ground lock output.
Connect the red wire to the wire that provides a low current ground signal from the factory door lock switch
to the factory door lock control relay.
The green wire provides the first ground pulse during unlocking, or the drivers door pulsed ground
unlock output. Connect this wire to the drivers door unlock relay that requires a low current ground
signal to unlock only the drivers door. If the vehicle does not have a separate drivers door relay, one will
have to be added. Locate the drivers door unlock motor wire and cut it at a convenient location to allow
wiring of an optional relay. Connect the door side of the cut wire to terminal 30 of the optional relay added.
Connect the vehicle side of the cut wire to terminal 87a of the optional relay added. Connect the green wire
of the 3 pin harness to terminal 86 of the optional relay added. Connect terminal 85 of the optional relay
added to a fused constant + 12 volt source. Most vehicles door lock/unlock motor legs rest at ground, and
switch +12 volts to the door lock/unlock motor legs for operation, if this is the case in the vehicle you are
working on, connect the remaining terminal, 87, to a fused + 12 volt source. In the rare instance that the
vehicle door lock/unlock motor legs rest at + 12 volts and switches ground to the door lock/unlock motors,
connect the remaining terminal, 87, to chassis ground.
The Red/Black wire provides a pulse ground output when the unlock button of the transmitter is pressed
a second time after unlocking. Connect the Red/Black wire to the wire that provides a low current ground
signal from the factory door unlock switch to the factory door unlock control relay.
9
3 Wire Positive Switched 2 Step Door Locks
The green wire provides a positive pulse during locking, or the pulsed + 12 volt lock output. Connect
the green wire to the wire that provides a low current positive signal from the factory door lock switch to
the factory door lock control relay.
The red wire provides a positive pulse during unlocking, or the drivers door pulsed positive unlock
output. Connect this wire to the drivers door unlock relay that requires a low current positive signal to
unlock only the drivers door. If the vehicle does not have a separate drivers door relay, one will have to be
added. Locate the drivers door unlock motor wire and cut it at a convenient location to allow wiring of an
optional relay. Connect the door side of the cut wire to terminal 30 of the optional relay added. Connect
the vehicle side of the cut wire to terminal 87a of the optional relay added. Connect the red wire of the 3
pin harness to terminal 86 of the optional relay added. Connect terminal 85 of the optional relay added to
chassis ground. Most vehicles door lock/unlock motor legs rest at ground, and switch +12 volts to the
door lock/unlock motor legs for operation, if this is the case in the vehicle you are working on, connect the
remaining terminal, 87, to a fused + 12 volt source. In the rare instance that the vehicle door lock/unlock
motor legs rest at + 12 volts and switches ground to the door lock/unlock motors, connect he remaining
terminal, 87, to chassis ground.
The Red/Black wire provides a pulse ground output when the unlock button of the transmitter is pressed
a second time after unlocking. Because the vehicle you are working on requires a positive pulse from the
factory door lock switch to the factory door lock control relay, you will have to add a relay to invert the
output polarity of this wire. Connect the Red/Black wire to terminal 86 of the optional added relay.
Connect terminal 85 & 87 to a fuse + 12 volt source. Connect terminal 30 to the low current door unlock
wire from the factory door switch to the door unlock control relay.

Resistive Circuits, As Well As 4 Wire Polarity Reversal and 5 Wire Alternating 12 Volt
Door Lock Control Circuits
These applications require the use of additional components which may include relays, fixed resistors, or
for convenience, the AS 9159 Door Lock Interface. Refer to the AUDIOVOX Door Lock Wiring Supple-
ment and or the Audiovox fax back service for information on your particular vehicle for properly connect-
ing to these types of circuits.
2 Pin Blue Connector: Programming Switch
Route the grey and black wires in the 2 pin connector from the previously installed programming switch to
the control module and plug it into the mating blue connector on the side of the module.
WIRING THE 4 PIN AUXILIARY OUTPUT HARNESS
The auxiliary 4 pin connector provides low current outputs to control various functions in the vehicle
during different stages of the Remote Start unit's operation. Understanding these outputs and the time in
which they occur will allow you to determine if they are needed for the particular vehicle you are working
on as well as how to use them.
Black w Blue Trace Wire: Pulsed Ground Output Before Start
The Black w/ Blue Trace wire will provide a 1 second 300 mA pulsed ground output 1.5 second before the
remote start unit activates as well as when the transmitter is used to unlock the system. Typical use for
this output would be to disarm a factory theft deterrent system to prevent false triggering of the factory
alarm when the remote start unit engages or when the APS-675 is used to unlock the doors.
Black w/ Light Green Trace Wire: Pulsed Ground Output After Start
The Black w/ Light Green Trace wire will provide a 1 second mA pulsed ground output after the vehicle is
started under control of the remote start unit. Typically this wire will be used to re-lock the vehicle doors if
the doors unlock automatically when the factory anti-theft system is disarmed.
Black w/ Red Trace Wire: Pulsed Ground Output After Shutdown
The Black w/ Red Trace wire will provide a 1 second 300 mA pulsed ground output after the remote start
unit shuts down. This output will occur regardless of whether the circuit times out or is manually termi-
nated. Typically this output will be used to re-lock the vehicle doors if the doors unlock automatically
when the ignition circuit transitions to off.
11
Black w/ Yellow Trace Wire: Ground Output During Start (Crank)
The Black w/ Yellow Trace wire will provide a 300 mA ground output while the starter output of the remote
start unit is active. This output can be used to activate the Crank Low/Bulb Test wire found in some GM
vehicles. This wire is also referred to as the ECM wake up wire in some Chrysler vehicles.
NOTE: The outputs above are low current outputs and must be used with a relay if the circuit's requirement
is more than 300 mA.

Channel 3 Relay Wiring Detail
From 2 Pin Harness
Green w/ Black Trace Wire: 300mA Latched Channel 4 Output
The Green w/ Black Trace wire supplies a 300mA switched output whenever channel four of the receiver is
accessed. Pressing the pre-programmed transmitter button(s) will access channel four and will remain
active, for up to 8 seconds, as long as the transmitter button(s) is held. This is a low current output and must
be connected to a relay to supply power to the device you intend to control. Connect Green w/ Black Trace
wire to terminal #86 of a VF45F11 P&B relay or equivalent. Connect terminal #85 of the relay to a
fused + 12 volt source. Connect the common, normally open, and normally closed contacts of the relay to
perform the selected function of the channel 3 output.
WARNING ! Connecting the dark green w/black trace wire to any high current switched output
(300mA max.) will damage the control module.

Dark Blue/Black and Green/White - 2 Pin Input/Output Harness:
Dark Blue/Black Trace Wire: External Trigger Input
The Dark Blue/Black trace wire allows the remote start unit to be activated from an external source. The
intent of this wire is to allow the unit to be controlled from a "POSSE/CAR-LINK" paging system or similar
device. When this wire receives a ground pulse, the unit will start the vehicle. Connect this wire to a
ground pulsed output from the controlling circuit.
Green w/ White trace Wire: Entry Illumination Ground Output
This wire provides a 30 second ground output (300 mA Max.) whenever the remote is used to unlock the
doors . This wire should be connected to an external relay, and wired to the vehicles interior entry lighting
whenever the optional Interior Illumination circuit is desired. See below for relay wiring details.

TIMED START PROGRAM:
The Remote Start unit has the ability to start the vehicle automatically at timed intervals. This feature is
useful in extremely cold climates where starting the engine is the only means to keep the battery charged
and fluids warm. The operator has the option to have the unit start every 2 or 4 hours for a maximum of
48 hours. Factory pre-set is to start at 4 hour intervals. To select 2 or 4 hour automatic start timer:
1. Start with the Enable switch (Red Handle) in the "On" Position.
2. Turn the ignition on then off.
3. Within 10 seconds of the key turning off, cycle the enable switch Off, On, Off, On ( 2 times) to select a
2 hour timed start interval. Cycle the enable switch Off, On, Off, On, Off, On, Off, On (4 times) to select
a 4 hour timed start interval. The lights will flash 2X or 4X dependant upon 2 or 4 hour interval setting.
NOTE: Once selected, 2 or 4, this timer interval will remain in memory until it is manually changed. To
change, the above sequence will have to be followed.
TIMED START OPERATION:
To begin the start timer, within 10 seconds of turning off the ignition switch, activate the RF command to
start 2 times. (Press the trunk/key button 4 times). The lights will flash 4 times. Indicating timed interval
mode has been initiated. The vehicle will automatically start every 2 or 4 hours as programmed. To cancel
the timed start mode start the vehicle either by RF or by the ignition key.
Multi Coil Pack Adaptor: (Optional)
IF REQUIRED, The multi coil pack adaptor, (P/N 136B1400), is designed for use with vehicles where
single point ignition coil or single injector cannot be learned or single point tach signal is unavailable.
To use the adaptor, the Green/Black wires must connect to the negative side of the ignition coil(s).
1. For vehicles utilizing independent coils per cylinder, connect the three Green/Black leads to alternate
coils. To achieve optimum performance the coil signals must be evenly distributed. This is accom-
plished by first mapping out the firing order of the engine in groups of as indicated below. Draw a
circle around any of the columns. The Green/Black wires should be connected to the negative (-)
terminal of the respective cylinder number which appears in any of the circles.
2. For vehicles utilizing 2 cylinder firing per coil pack, connect Green/Black to the tach side of each coil
pack. For 8 cylinder, four coil systems, connect to any of the three coils.
3. Connect the Yellow wire to a +12 volt ignition 1 source. This wire will have +12 volts with the ignition
in the on and start position and have 0 volts with the ignition in the off position.
4. Connect the Green wire to the (Green) or (Orange/Green) tach input of the Audiovox remote start
unit.
TESTING YOUR INSTALLATION:
CAUTION!! The following procedure must be performed after the installation of an Audiovox Remote
Start Device. It is the responsibility of the installing technician to complete these tests. Failure to test the
unit in the following manner may result in personal injury, property damage, or both.
HOOD PIN SAFETY SHUT DOWN:
The intention of the hood pin safety shut down is to prevent the Remote Start unit from being activated
while a mechanic or vehicle owner is performing normal routine vehicle maintenance.

15
1. With the driver's window in the down position, start the vehicle using the RF transmitter.
2. Reach inside the car and pull the hood release.
3. Raise the hood and confirm that the remote start unit shuts down.
If the unit fails this test, recheck your pin switch connection to the Gray/Black wire of the Audiovox Remote
Start Unit.
DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE
OPERATION OF THE HOOD PIN SAFETY SHUT DOWN FEATURE.
MANUAL SHUT DOWN / ENABLE CIRCUIT:
The intent of the manual shut down / enable circuit is to allow the vehicle operator to prevent operation of
the Remote Start Unit regardless of the RF transmitter operation.
To test the integrity of the manual shut down / enable circuit:
1. Place the control switch in the on (Closed To Ground) position.
2. Start the vehicle using the RF transmitter.
3. The vehicle should start and run under the control of the remote start unit.
4. Move the switch to the off (Open From Ground) position, the vehicle should shut off.
If the unit fails this test, recheck your enable switch connection to the Ground and the Black/White wire of
the Audiovox Remote Start Unit. If you have a plug in enable switch, check that the two pin connector is
firmly seated in the mating connector on the control module.
DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE
OPERATION OF THE MANUAL SHUT DOWN / ENABLE FEATURE.
NEUTRAL START SAFETY TEST:
The intent of the neutral start switch is to prevent the vehicle from starting while the gear selector is in any
position other than Park, or Neutral. When installing a Remote Start Device, it is imperative that the Yellow
Starter wire be connected to the ignition switch side of the Neutral Start Switch. Consideration for the
placement of a starter inhibit relay is important as well, and should be connected to the ignition switch side
of the Yellow Start Wire.
To test the integrity of the Neutral Start Safety Circuit:
1. Set the vehicle parking brake.
2. Block the drive wheels to prevent vehicle movement.
3. Temporarily disconnect the Brown/Black positive shut down wire from the vehicle's brake switch.
4. Sitting in the vehicle, start the engine using the vehicle's ignition key.
5. Step on the brake pedal and shift the gear selector into reverse.
6. Allow the transmission to shift. When you feel the engine pull, do not move the gear selector just turn
the ignition switch off. DO NOT attempt to remove the key.
7. Keeping the brake pedal depressed, activate the RF transmitter in an attempt to start the vehicle. The
car should not start.
8. Repeat the above test this time move the gear selector to the drive position. If the unit attempts to start,
failing this test, recheck your Yellow Wire's connection. This wire must be connected to the ignition
switch side of the Neutral Start Switch. If the vehicle you are working on does not have an Electrical
Neutral Safety Switch, it will be necessary to reconfigure the Remote Starts Wiring to accommodate
this vehicle. The information concerning the Mechanical Neutral Safety Switch provided below will help
you to determine if the vehicle you are working on has this type of safety switch and will provide
alternate wiring methods to accommodate this situation.

DISCONNECTED IN STEP 3
DO NOT RELEASE THIS VEHICLE TO THE CONSUMER UNTIL YOU CONFIRM THE OPERATION
OF THE NEUTRAL SAFETY START FEATURE.
MECHANICAL NEUTRAL SAFETY SWITCH CONSIDERATIONS:
Mechanical neutral safety switch configurations differ slightly in that they do not offer the same level of
safety when installing a remote start device. Often when the ignition switch is turned off while the gear
selector is in any position other than park or neutral, the mechanical function will not allow the key to be
turned to the start position or be removed from the ignition cylinder. This configuration prevents mechani-
cal operation while the vehicle is in gear but offers no consideration for electrical operation. Because of
this potential problem, this installation requires the additional connection of a safety wire from the remote
start device to the vehicle Park/Neutral ECM Input or the vehicle key in sensor. This connection will
prevent remote start operation if the key is left in the ignition switch regardless of the gear selectors
position.
PARK / NEUTRAL ECM INPUT:
The Park / Neutral ECM input is the preferred method of installation. This not only maintains the integrity
of the factory circuit, it is also the easiest to install, providing the vehicle you are working on has this
ECM input.
The installation required for this application (shown below), indicates the slight reconfiguration of the
control switch wiring and the addition of a 4000 series diode. Shown is a typical GM Park/Neutral ECM
input circuit. To connect the Audiovox remote start unit to the GM Park / Neutral ECM input:
1. Locate the Orange / Black reference wire in the "C2" connector found at the ECM in GM B Body
vehicles or, locate the equivalent reference wire in the vehicle you are installing the Audiovox Remote
Start Unit in.
2. Connect the Cathode, (Striped) end, of a 4000 series diode to this reference wire.
3. Connect the Anode, (Non Striped) end, of the diode to one side of the Remote Starts enable switch.
4. Connect the other side of the enable switch to the Black/White enable input wire of the Remote Start
unit.
The reference diagram below shows a typical GM B Body ECM reference wire and how it is to be
connected to the Remote Start Unit.

KEY IN SENSOR CIRCUITS:
If the vehicle you are working on does not have or you cannot locate the ECM reference wire, there are
two alternatives available. Although not preferred, the vehicle Key In Sensor may be reconfigured to allow
a margin of safety and will prevent the vehicle with a Mechanical Neutral Start Switch from starting in gear.
AUDIOVOX ADVISES THAT YOU MAINTAIN THE FACTORY CIRCUIT WHENEVER POSSIBLE. The
following two circuits may be used only if the above circuit is not available.
NOTE: When completing an installation using either of the following key in sensor circuits, if the operator
inserts the ignition key while the vehicle is running under the control of the Remote Start, the
vehicle will shut down. This must be explained to the operator as it is in contrast to the normal
operation of a vehicle utilizing an electrical neutral start switch and is inconsistent with the opera-
tors manual.
Additional information concerning Key In Sensor methods 1 & 2 are listed below and should be reviewed
before considering either alternative.
Method 1 will allow the safety required for the remote start unit and prevent the vehicle from starting while
in any gear other than Park or Neutral while the key is in the ignition cylinder however, if the key is left in
the ignition switch and the door is left opened, the added relay will be energized causing a 150mA drain on
the battery.
Method 2 will allow the safety required for the remote start unit and prevent the vehicle from starting while
in any gear other than Park or Neutral while the key is in the ignition cylinder however, the original factory
key in chime module will not alert the owner that the key has been left in the ignition switch. In addition,
this may also effect other warning tones such as the light on reminder.
These situations should be carefully considered before altering the vehicle's wiring and must be fully
explained to the consumer.
METHOD 1
To connect to the key in sensor as shown in method 1:
A. Locate the control wire that connects the drivers door pin switch to the key in sensor switch.
B. Cut this wire and connect the ignition cylinder side to chassis ground.
C. Locate the key in sensor switch wire that connects the chime module to the ignition cylinder .
D. Cut this wire and connect the ignition cylinder side to terminal 30 of a P&B VF45F11 or equivalent relay.
E. Connect the cathode (striped) side of a 4002 series diode to this same wire, and connect the (non
striped) side to the negative shut down safety wire (Gray / Black) of the Audiovox Remote Start Unit.
F. Connect terminal 86 of the relay to a fused +12 volt constant battery source.
G. Connect terminal 87 of the relay to the Chime Module side of the previously cut wire in step D.
H. Connect terminal 85 of the relay to the Drivers Door side of the pin switch wire previously cut in step B.
NOTE: A second 4002 series diode may be required to maintain the integrity of the hood open, shut down
circuit. If this is the case, it must be installed as shown in the diagram above. The anode (Non
Striped) side must be connected to the Gray/Black wire of the Remote Start Unit. The cathode
(Striped) side must be connected to the hood pin switch. If the hood pin switch is also used for an
alarm trigger input, be certain to use the dual diode assembly packaged with the Audiovox Re-
18
mote Start Unit as shown below.
METHOD 2
To connect to the key in sensor circuit as shown for method 2:
A. Locate the control wire that connects the drivers door pin switch to the key in sensor switch.
B. Cut this wire and connect the ignition cylinder side to chassis ground.
C. Locate the key in sensor switch wire that connects the chime module to the ignition cylinder .
D. Cut this wire and connect the ignition cylinder side to the Remote Start Negative Safety Shut down
Wire Gray/Black, using a 4002 series diode as shown above.
NOTE: A second 4002 series diode may be required to maintain the integrity of the hood open, shut down
circuit. If this is the case, it must be installed as shown in the diagram above. The anode (Non
Striped) side must be connected to the Gray/Black wire of the Remote Start Unit. The cathode
(Striped) side must be connected to the hood pin switch. If the hood pin switch is also used for an
alarm trigger input, be certain to use the dual diode assembly packaged with the Audiovox Re-
mote Start Unit as shown in this installation guide. (Page 9)
AFTER THE CONNECTION OF THE NEUTRAL START SAFETY WIRE AS INDICATED IN ANY OF THE
PREVIOUS ALTERNATE CONFIGURATIONS, THIS CIRCUIT MUST BE TESTED FOR OPERATION.
Retest by following the steps outlined in the NEUTRAL START SAFETY TEST shown in this manual.
COMPLETING THE INSTALLATION:
After you have confirmed the operation of the Audiovox Remote Start unit and tested all the safety fea-
tures of the system:
1. If you have not done so already, place the red rubber handle cover over the handle of the control switch
for ease of identification. This will allow your customer to distinguish the Remote Start control switch
from the program switch.
2. Mount the control module up and behind the dash securing it in place with cable ties or screws. Be
certain that the chosen mounting location will not inhibit any of the controls of the vehicle.
3. Securely harness and tie all wiring up and away from all hot and moving parts that they may come in
contact with under the dash board or in the engine compartment areas.
CAUTION: Particularly avoid the area around the steering shaft and column, as wires can wrap around
these mechanisms and impair the safe operation of the vehicle.
4. Apply the Caution Labels supplied with this kit to a conspicuous area in the engine compartment. Make
sure to clean the surface before affixing the label.
5. Check the vehicle's wipers, lights, horn, etc.... to insure proper operation.
6. Replace all panels that were removed during installation, and retest the system.
7. Explain all activated features and safety systems associated with Remote Start Unit installed to the
customer.
