shielded window glass as far as possible. There might be an area of the windshield that does not have
protection.
H8. 10-PIN MINI CONNECTOR WIRE HARNESS.
H8/1. Yellow wire – To Ignition Sw12V –
This wire is connected to a switched 12 volts source. This wire should receive "12 volts" when the ignition
key is in the "ON" and "START" position. When the ignition is turned "OFF", this wire should receive "0"
voltage.
H8/2. Blue / White wire – (-) Instant Trigger or Major trigger Input (Zone 2) –
This wire is the ground trigger input wire for hood/trunk pin switches.
H8/3. Violet wire – Positive Door Switch Sensing Input –
This wire is the positive trigger input wire for positive door pin switch. This wire is the connection for
"positive" type factory door pins (typical of Ford vehicles). Locate the "common wire" for all door pins and
make the connection of the Violet Wire here.
H8/4. Green wire – Negative Door Switch Sensing Input –
This wire is the ground trigger input wire for negative door pin switch. This wire is the connection for
"grounding" type factory door pins. Locate the "common wire" that connects the door pin switches. Make
the connection of the GREEN Wire here.
H8/5. Orange wire – (-) 200mA Grounded Output When Armed –
This wire will become grounded when the alarm is armed. The current capacity of this wire is 200mA. This
output can control the starter disable, when an intrusion is detected and the system is triggered. The
vehicle is prevented from any unauthorized starting.
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). If extended wires are needed, they must be exactly the 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 ORANGE Wire from the control module to the ORANGE wire (pin #86) of the relay.
f). Connect the ORANGE wire (pin #85) of the relay to a switched 12 volts source from the ignition switch.
NOTE: If more than one electronic device will be connected to the ORANGE Wire, it will be necessary to
isolate the connection of each device control wires with a 1N4003 diode.

H8/6. Brown / Black wire – (-) 200mA Horn Output –
This wire is provided to use the existing vehicle's horn as the alarm system's optional 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.
H8/7. Light Green / Black wire – (-) 200mA 2-Step Door Unlock Output –
The 2-step door 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, pressing the disarm (or unlock) button one time will disarm
the alarm and unlock the driver's door only. If, you press the disarm (or unlock) button two times within 3
seconds, the alarm will disarm and all the doors will unlock.
H8/8 Purple / Black wire – (-) 200mA Channel 4 Programmable Output –
This wire is built-in user-programmable timer output provides a ground through this wire. Press the
transmitter
and
buttons 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!
