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.

DARK BLUE/BLACK TRACE Wire: Trigger Input
The Dark Blue/Black trace wire is the trigger input wire. When this wire receives a pulse ground from the
controlling remote circuit, the remote start unit to activate. Connect this wire to a ground pulsed output from
the controlling circuit. (When upgrading a factory keyless entry system, do not use this wire. See information
concerning the 3 pin upgrade connector found later in this manual)
DARK GREEN/ORANGE Wire: TachSensor 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. (See programming information shown later in the manual)
