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.

Tachometer Input Wiring Detail
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.
