3. Wiring
Keep the wiring away from moving engine parts, exhaust pipes and high tension cable. Tape
wires that pass through holes in the bodywork to prevent fraying. Watch out for sharp edges
that may damage wires and cause short-circuits.
A. Main Wiring
1. Red wire – System power (+12V constant)
The red wire supplies the system with power. Connect this wire with a +12V source from the
fuse block.
ATTENTION : If you plan to program the alarm with current sensing capability, this connection
must be made at the permanent +12V live point of the fuse that controls the
interior dome light of the vehicle as it is this connection that detects voltage drop.
2. Black wire – System ground
This is the 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 directly to the frame of the vehicle.
3 & 4. Yellow wire – Ignition switch power
Find the wire coming from the ignition key that supplies the ignition coils. Cut the wire in half
and try to start the vehicle. If you have found the correct wire, the engine will crank over but
won't start. When you have found the correct wire:
1) Connect one yellow wire with the cut half of the ignition wire.
2) Connect the second yellow wire with the other half of the ignition wire.
5. Black / white wire – LED indicator connection
This is the special output wire for the connection of the alarm's LED status indicator supplied
with this alarm system. Connect the black/white wire with the black wire from the LED indicator.
Connect the red wire from the LED indicator to a constant +12V source.
6. Orange wire – Negative power output 500mA
This wire becomes grounded when the alarm is armed. The current capacity of this wire is
500mA. It can be connected to optional modules such as sunroof control, optional starter
interruption, etc.
7. Red/white wire – Parking light power
This is the COM point of the parking lights.
8 & 9. White wire – Flashing parking light (+12V 5A output)
When the alarm is triggered, the two white wires provide a pulse of +12V, 5A output. Connect
the two white wires with the right and left indicator lights.
