This wire provides a 500 mA + 12 Volt transistorized output when the ignition key is turned to the “ON” position, and 0
Volts when the ignition key is “OFF” and when the vehicle is running under the control of the remote starter.
This wire should be connected to the ignition input of the alarm system.
The Yellow w/ Black wire output will allow you to remote start the vehicle while leaving the alarm armed.
(2) WHITE Wires: Parking Light Flasher
These wires are the COMMON and NORMALLY OPEN contacts of the on-board parking lamp relay.
If the vehicle's parking lights are a +12 volt switched system, connect (1) of the White wires to a fused (15A max.) +12
volt battery source, and connect the second White wire to the vehicle's parking light wire.
If the vehicle's parking lights are a chassis ground switched system, connect (1) of the White wires to a chassis ground
source, and connect the second White wire to the vehicle's parking light wire.
LIGHT BLUEWire: Ignition3 /Shock DisableOutput
This is a 500 mA transistorized ground output, andan external relay will be required in all cases that this output is needed.
NOTE: This Light Blue wire is energized 3 seconds before the PRO- 9171FT starts the engine. This wire remains
energized for 4 seconds after engine shut down.
The Light Blue output serves the following functions.
A. Shock Sensor Override: If the alarm is connected to a shock sensor, then the vibration caused by remote starting
the vehicle may trigger the alarm. If this is the case, connect the Light blue wire to terminal 86 of an external relay. Connect
terminal 85 of the relay to a fused + 12 Volt battery source. Cut the trigger wire from the shock sensor, and connect one
side of the cut wire to terminal 30 of the relay. Connect the other side of the cut wire to terminal 87a of the relay. Just
before the remote starter is activated, the relay contacts will open, and the shock sensor will not trigger the alarm. Four
seconds after the remote start unit shut down the shock sensor will be operational.
B. Ignition 3 Output: Some newer vehicles use a third ignition wire, which is necessary to keep the engine running. If
this is the case, connect the Light Blue wire to terminal 86 of an external relay. Connect terminals 85 and 30 together
toa+12Volt battery source that is fused for a minimum 25 A rating. Connect terminal 87 of the external relay to the third
ignition wire in the vehicle.
C. G.M. VATS Key Override: If the vehicle has the General Motors VATS system installed, you will need to by-pass the
starter cut portion of the VATS system. To do this;
1. Measure the resistance of the ignition key, and get a resistor which value is within 5% of the key value.
2. Locate the pair of VATS wires in the vehicle, usually a pair of thin gauge wires running from the ignition switch to
the VAT 1 Control Unit.
NOTE: These wires are typically White w/ Black tracer and Violet w/ Yellow tracer, however in late 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 Starter to terminal 86 of an external relay. Connect terminal 85 of the
relay to a fused + 12 Volt battery source.
4. Cut (1) of the VATS wires, and connect the ignition switch side of the cut wire to terminal 87a of the relay. Connect
the other side of the cut wire to terminal 30 of the relay.
5. Connect the resistor from terminal 87 of the relay to the second VATS wire.
