PROFESSIONALINSTALLATION
STRONGLYRECOMMENDED
Installation Precautions:
Roll down window to avoid locking keys in vehicle
during installation
Avoid mounting components or routing wires near
hot surfaces
Avoid mounting components or routing wires near
moving parts
Tape or loom wires under hood for protection and
appearance
Technical Support [phone]
or go to
http://techservices.codesystems.com
Use a Digital Multi Meter for testing and verifying
circuits. DO NOT USE A TEST LIGHT, OR
"COMPUTER SAFE PROBE" as these can set off air
bags or damage vehicle computers.
Use grommets when routing wires through metal
surfaces

1 BLUE/BLACK IGNITION 3 / ACTIVE OUTPUT ( - )
The Active Output/Ignition 3 output wire provides a ground output when the remote
start function is activated and remains until 4 seconds after the remote start is
shutdown. The Ignition 3 output wire can be used for several functions listed
below. If this wire will be used for multiple application's a 1 amp diode is required
in-line with the stripe facing the control module.
Factory transponder (coded key) bypass.
General Motors VATS bypass, see the following diagram. Use an SPDT relay (not
supplied).
Ignition 3 output, see the following diagram. Use an SPDT relay (not supplied).

2 PURPLE/WHITE TACH INPUT
Locate the vehicle’s ignition coil or fuel injector in the engine compartment.
Verification: Test using the following procedure:
1. Set voltmeter to AC VOLTS.
2. Attach positive lead of a volt meter to a constant 12-volt source.
3. Attach negative lead of a volt meter to the wire to be tested.
4. Start the engine.
5. Have someone press on the gas pedal slightly as you monitor the meter. If
connected to the correct wire, the voltage reading will increase as the engine’s
RPM increases.
Connect the PURPLE/WHITE wire to the negative side of the vehicle ignition coil
or fuel injector.
3 GRAY HOOD PIN INPUT ( - )
Install a Hood Pin Switch and connect to the GRAY wire. This connection is
required for Remote Start.
Verification: This wire when connected will register ground when the
vehicle's hood is opened.
Connect the GRAY wire to the hood pin.
NOTE: Be sure to loom the wire, and seal the grommet.
4 BROWN/RED BRAKE INPUT ( + )
Locate the vehicle’s brake light wire at the brake pedal mounted switch.
Verification: This wire registers positive voltage when the brake pedal is
pressed.
Connect the BROWN/RED wire to the vehicle’s brake light wire.

72010AudiovoxElectronicsCorporation.Allrightsreserved.
1 BLACK GROUND
Connect the BLACK wire to a solid chassis ground point using a ring terminal and
self tapping screw (not supplied). Scrape away paint from the grounding point to
ensure a good connection. The recommended grounding point is a metal surface
in the driver’s side kick panel area.
NOTE: Do not ground the BLACK wire with any other vehicle components.
3 Pin Parking Light Harness
2 WHITE/RED PARKING LIGHT INPUT
3 WHITE PARKING LIGHT OUTPUT
Locate the parking light output wire at the vehicle’s light switch.
Verification: This wire registers positive voltage when the parking lights are
turned on.
Positive switching Parking Lights:
Connect the WHITE/RED wire to a 15 Amp max fused battery source.
Connect the WHITE wire to the parking light output wire.
Negative switching Parking Lights:
Connect the WHITE/RED wire to a good chassis ground.
Connect the WHITE wire to the parking light output wire.

6 Pin Start Harness
1 PURPLE STARTER OUTPUT ( + )
Locate the vehicle starter wire.
Verification: This wire registers voltage only when the key is turned to the
START position.
Verification:
The starter wire registers voltage when the key is turned to the
START position.
Connect the PURPLE wire to the MOTOR SIDE of the vehicle starter wire.
2 RED BATTERY 12V ( + )
Locate 1 of the vehicle’s constant 12 Volt battery wires at the ignition switch.
Verification: This wire will register ( + ) voltage in all positions of the ignition
switch.
Connect the RED wire to the constant 12 Volt battery wire.
NOTE: Remove all fuses until all connections are made.
3 ORANGE ACCESSORY 1 ( + )
Locate the vehicle’s accessory wire at the ignition switch.
Verification: This wire registers voltage when the key is turned to ACC
(Accessory) and the ON (or RUN) position. The voltage drops out when the
key is turned to the START(or CRANK) position.
