a). Find the wire from the starter solenoid, (usually located on the starter) and going to the ignition switch. 
b). When found, use voltmeter, connect one probe of the voltmeter to ground and connect the other end of 

the probe to the starter wire, it should receive "12 Volts" only when the ignition key in the "START" 
position. 

c). After locating the correct wire, cut it in half, try to start the vehicle. The engine should not "crank over". 
d). When the extend wires are needed, they must be exactly same gauge as the cut wire. Connect the cut 

wire from the key switch to the RED wire (pin #30) of the relay, and connect the starter wire to the 
WHITE wire (pin #87a ) of the relay. 

e). Connect the H3/5 ORANGE Wire from the control module to the ORANGE wire (pin #86) of the relay. 
NOTE: If more than one electronic device will be connected to the H3/5 ORANGE Wire, it will be 
necessary to isolate the connection of each device control wires with a 1N4003 diode.

 (Factory default setting) 

This will become a 1 second pulse ground by press and hold the button II on transmitter for two seconds, 
the current capacity of this wire is 200 mA. this feature allows you to remote control trunk release or 
other electric device.

Programming to “2 Step Door Unlock Output) 

 

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 button II one time will disarm the alarm and unlock the 
driver's door only. If, press button II two times within 3 seconds, the alarm will disarm and all doors will 
unlock. 

     

PAGER OUTPUT

 (Set Feature 

III – 2

 

Programming to “PAGER Output)   

This wire provides a negative output, when the alarm triggered. The current capacity of this wire is 
200mA. For optional electrical device in this system, please connected to an additional relay. (I.E. Pager 
interface....) 

H4: RF ANTENNA - BLACK THIN WIRE 

The black thin wire on control module is the receiver antenna wire. Antenna placement is very important! 
Ensure that it is unwrapped and stretched out with the last 6" straight and keep it away from large metal 
objects or chassis for best reception.
