8. Connect the pin (86) of the relay module to the ignition wire from the ignition switch.
9. connect the pin (85) of the relay module to the H5/2 Yellow wire of 5-pin mini white connector.
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).

H5/3. WHITE Wire – (-) 200ma PROGRAMMABLE OUTPUT
(See Alarm Feature I - 4 Programming)
DOME LIGHT CONTROL OUTPUT (Factory Default Setting)—
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.
a). Upon disarming, the interior lights will remain on for 30 seconds.
b). If the vehicle is violated, the interior light will flash for the same duration as the siren.
CHANNEL 4 OUTPUT–
(See Alarm Feature I - 5 Programming)
Press and buttons at the same time to remote control the optional electrical device. The device will
'on' when the button(s) press continuously, and 'off' when the button(s) released.
GROUND OUTPUT DURING START (CRANK) –
(See Alarm Feature I - 5 Programming)
This wire will provide a 200mA ground output while the starter output of the remote start unit is active. This
output can be used to activate the Crank Low/Bulb Test wire found in some GM vehicles. This wire is also
referred to as the ECM wake up wire in some vehicles.
H5/4. PINK Wire – (-) 200ma PROGRAMMABLE OUTPUT
(See Alarm Feature I - 3 Programming)
2 STEPS UNLOCK OUTPUT (Factory Default Setting) --
The 2 steps unlock feature will work for the most fully electronic door lock circuit. The vehicle must have
an electronic door lock switch (not the lock knob or key switch), which locks and unlocks all of vehicle's
doors. When wired for this feature, press the disarm (or unlock) button one time will disarm the alarm and
unlock the driver's door only. If, press disarm (or unlock) button two times within 3 seconds, the alarm will
disarm and all doors will unlock.
FACTORY SECURITY DISARM SIGNAL OUTPUT –
This wire is designed to disarm a factory installed security system. This wire sends a negative (-) 1
seconds pulse upon a remote start and remote door unlocking. Some factory systems must be disarmed
to allow remote starting. In most cases, this wire may be connected directly to the factory alarm disarm
wire. The correct wire will show nagative ground when the key is used to unlock the doors or trunk. This
wire is usually found in the kick panel area in the wiring harness coming into the car body from the door.
START STATUS (Shock Sensor Bypass Control) OUTPUT–
This wire is designed to by-pass shock sensor module. This wire will supply an output at all times the
remote start is operating plus an additional 3 seconds after the remote start unit turn off.
