YELLOW WIRE: (-) 200ma IGNITION 3 OUTPUT –
This wire provides a 200mA (-) ground output that becomes active 4
seconds before the remote start unit is initialized, and remains grounded
while running.
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, wire an IGN 3
relay (not supplied) as shown below:
Do not connect any vehicle circuits together; they are isolated for a
reason. See diagram next page.

GM VATS KEY OVERRIDE:
If the vehicle has the General Motor 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.
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.
3. Connect the YELLOW wire from Remote Start Unit to Terminal #85 of
the relay. Connect terminal #86 of the relay to a fused +12 volt.
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).
