    If the vehicle has transponder 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.  You will need a transponder key that's already programmed to the vehicle. 
2.  Remove the trim around the ignition switch. 
3.  Wrap a thin (28 - 30awg) wire tightly around ignition switch 6 to 8 times and secure it. 
4.  About 6"down line make another loop of approximately 2"diameter. 
5.  Place the key inside this loop and secure it to the loop. 
6.  Connect on end of the (28 - 30awg) wire to pin (87) of the relay module. 
7.  Connect the other end of the loop wire to Pin (30) of relay module. 
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

.

 

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. 

Horn Output–

 

 

(See Alarm Feature 

III - 2

 Programming) 

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–

(See Alarm Feature 

III - 2

 Programming)

 

This wire is designed to 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.. 

Ground Output During Start (Crank) – 

See Alarm Feature 

III - 2

 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 

III - 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
