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 an external 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 selseced resistor from terminal #87 to the second(#2) wire (as shown).

This wire is built-in user-programmable timer output provides a ground through this wire. Press the
transmitter
and
button at the same time. You may program the built-in timer to send a ground
signal for any time interval between 1 second and 2 minutes. For instance, this timer output may be
used to turn on the headlight with the remote control. Also on certain BMW, Mercedes Benz, Jaguar
and Volkswagen cars, you can use this unique timed output to allow remote closure of all power window
and sunroof without the need for an external module!

Horn Output – (Factory default setting)
This wire is provided to use the existing vehicle's
horn as the alarm system's optional's warning
audible device. It's a transistorized low current
output, and should only be connected to the low
current ground output from the vehicle's horn
switch. When the system is triggered, the horn
will sound.

Factory Security Rearm Signal Output –
This output is programmable. If programmed rearm a factory installed security system. This wire will
supply a pulse whenever the remote start times out or is shut dowm using the transmitter and remote
door locking..
H8/4 White wire – (-) 200ma Dome Light Control Output –
This wire becomes grounded when the dome
light controls circuit active. The current capacity
of this wire is 200mA. This wire can control the
operation of the interior lights. An optional 10
Amps relay can be used to this system for interior
lights operation.
