Keep wiring away from moving engine parts, exhaust pipes, and high-tension cable. Tape wires that pass
through holes on the firewall to prevent frying electrical. Watch out for sharp edges that may damage wires
and causes short circuit.
CAUTION: Do not connect the wire harness to the control module until all wiring to vehicle is complete.
H1. MAIN 5 PIN WIRE HARNESS:
H1/1. Red / White Wire
– Parking Light Relay Input –
The RED/WHITE wire is the input to the flashing parking light relay. The connection of the RED/WHITE
wire will determine the output polarity of the flashing parking light relay.
If the vehicle you are working on has +12volt switched parking light, you do not need to connect this wire.
This wire already is connected to +12volt.
If the vehicles parking light is ground switched, cut the RED/WHITE wire and connect the RED/WHITE
wire to chassis ground.
H1/2. White Wire
– Parking Light Relay Output (+12 V 10A Output) –
Connect the WHITE wire to the parking light wire coming from the headlight switch. Do not connect the
WHITE wire to the dashboard lighting dimmer switch (Damage to the dimmer will result). The limitation of
the WHITE wire is 10 Amps max. Do not exceed this limit or damage to the alarm and parking light relay
will result.
H1/3. Black Wire
– System Ground –
This is main ground connection of the alarm module. Make this connection to a solid section of the vehicle
frame. Do not connect this wire to any existing ground wires supplied by the factory wire loom. Make the
connection to the vehicle's frame directly.
H1/4. Brown Wire
– Siren Drive or Horn Output –
(Set Feature
III
– 2
Programming)
SIREN DRIVE OUTPUT (Factory default setting)
This is the positive (+) output connection for the siren. Current capacity is 2 Amps. Make connection to
the (+) red wire from the siren. Make the (-) black wire coming from the siren to a good chassis ground.
(+) Low Current HORN OUTPUT -- (Set Alarm Feature III
– 2 To Horn Output)
This wire is provided to use the existing vehicle's horn as the alarm system's optional warning audible
device. It is a transistorized low current output, and should only be connected to the low current positive
(+) output from the vehicle’s horn switch.
H1/5. Red wire
– System Power (+12V Constant) –
The RED wire supplies power to the system. Connect this wire to a constant +12 volt source.
H2. NO USE
H6. NO USE
H7. BLACK 4-PIN CONNECTOR.

TRANSCEIVER/ANTENNA MODULE
The transceiver/antenna mounts on the location above the belt line (dashboard) of the vehicle for best
reception. We suggest you mount it on the lower left or upper left-hand side of the windshield.
Warning!
Do not mount in such a manner that it obstructs the driver’s visibility.
- Remove the protective tape backing.
- Carefully align the transceiver/antenna and apply to windshield.
- Route the black connector wire behind the trim and connect to the transceiver/antenna.
- Connect the other end to the control module.
- Special considerations must be made for type of windshield glass, as some newer vehicles utilize a
metallically shielded or infrared and UV radiation absorbing window glass that will inhibit or restrict RF
reception. In these vehicles, route the transceiver/antenna module away from metallic 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 Switched +12V –
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. NO USE
H8/3. NO USE
H8/4. NO USE
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.
