LIGHT BLUE Wire: Ignition 3 / Shock Disable Output
This wire provides a 300mA ground output that becomes active 3 seconds before the Remote Start Unit initializes, and
remains grounded while running plus an additional 4 seconds after the Remote Start Unit turns off. In all of the
applications described below, a relay will be required.
The Light Blue wire can be used to accommodate the following situations:
A. Shock Sensor By Pass:
If there is Shock Sensor used with an 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. Ignition 3 Output:
Some newer vehicles use a third ignition wire which is required 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 by-pass 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.
