THE TRANSCEIVER/ANTENNA ASSEMBLY:
The Superheterodyne Transceiver Antenna Assembly provided with this unit allows routing from below the dash-
board for maximum operating range. Choose a location above the belt line (dashboard) of the vehicle for best
reception. Special considerations must be made for windshield glass as some newer vehicles utilize a metallic
shielded window glass that will inhibit or restrict RF reception. In these vehicles, route the antenna toward a rear
window location for best reception. Secure the antenna with double stick tape provided. After securing the antenna
with tape, we advise also securing a section of the antenna cable to a fixed support. This will prevent the antenna
from dropping down in case the double stick tape is exposed to extreme heat, which may loosen its gummed
surface. Route the 4 pin connector toward the control module using caution not to pinch the cable as this will cause
poor or no RF reception to the control module.
I M P O R T A N T !
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 BAT-
TERY 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.
I M P O R T A N T !
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 ONTHAT LOAD. IFTHE VEHICLE, RUNNING UNDER LOAD WITHTHEAIRCONDITIONER,

TWO FUSES BE USED IN COMBINATION ON EACH POWER WIRE AS SHOWN BELOW. FORADDITIONAL INFORMA-
TION 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 (when used). For the electrical neutral
switch configuration, this connection must be made between the starter inhibit relay, (when used) and the
neutral safety switch as shown in the following diagram.

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 bypass 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. Connect 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.

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.
Tachometer Input Wiring Detail
Green/Yellow Wire: Diesel Wait To Start Input
The Green/Yellow wire will connect to a diesel vehicles glow plug wire. When the unit receives a start command, this
wire must go to + 12 then to ground to allow the crank sequence to begin. When ignition #1 is activated by the remote
start unit, the glow plug circuit gets energized, (+ 12 volts), when the glow plug circuit of the vehicle drops the + 12 volts,
whicheffectivelygroundsthewaittostartinput,then500mSlaterthestarterwillengage. Thiswirecanalsobeconnected
to the Glow Plug Bulb wire in the vehicle if this bulb wire gets + 12 volts when the ignition comes on and drops low when
the glow plug circuits temperature is reached. Be sure to fuse the wire with a 1 Amp Fuse when connecting to a high

If you are installing this unit in a Gasoline vehicle, this wire is not used.
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 disarm 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 transmitter 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 300mA 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 terminated.
Typically this output will be used to re-lock the vehicle doors if the doors unlock automatically when the ignition
circuit transitions to off.
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.

Multi Coil Pack Adapter: (Optional)
The multi coil pack adapter, (P/N 136B1400), is designed for use with vehicles that do not respond to single coil tach
programming. Although the tach resolution of this circuit is designed to interface direct with most vehicles, there may
be an occasion where the following circuit may be required.
To use the adapter, 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 accomplished 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.

W A R N I N G !!
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.

REMEMBER TO RECONNECT THE BROWN/BLACK WIRE TEMPORARILY
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 mechanical 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 selector 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 Start 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 operator's 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.
Circuits may be used only if the above circuit is not available.
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.
METHOD 1
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 Remote 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.

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.
4 Pin Upgrade Telematic Module:
Red = + 5 Volts, Black = Ground, White = Data TX, Yellow = Data RX
If used, connect the 4 pin harness from the Telematic one way module kit to the mating port on the controlling circuit.
NOTE: If using the TWO WAY Telematic module, only Ground, TX, and RX are used on this port, the + 12 volt supply
for the two way module must be sourced separately or the unit will not operate.
COMPLETING THE INSTALLATION:
After you have confirmed the operation of the Audiovox Remote Start unit and tested all the safety features 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.
8. Place the Valet Switch Tag and or the Remote Start Control Switch Tag on their respective switches and
point these out to the customer.
