A. Shock Sensor By Pass:
If there is a Non Plug in Shock Sensor used with the 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. Additional Ignition Output:
Some newer vehicles more than three ignition outputs 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 w/ White trace Wire:
Entry Illumination Ground Output
This wire provides a 30 second ground output (300 mA Max.) whenever the remote is used to disarm the
alarm or to unlock the doors and provides a continuous pulsed output whenever the alarm is triggered.
This wire should be connected to an external relay and wired to the vehicles interior entry lighting
whenever the optional Interior Illumination circuit is desired. See below for relay wiring details.
