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.

DARK GREEN 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.

2 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 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 particular vehicle do not exceed the rated 300mA output of the units door lock/unlock
circuit. Plug the two 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.
