Alarm wiring information

[VegaS10]

These are the most common wires used for our cars. Before you use any of these, test them with a multimeter or airbag safe test light.

12 volts = White (40 amps of current) located in the main ign. harness
Igniton = Black/yellow located in the main ign. harness
Starter = Black/white located in the main ign. harness
Accessory = Black/red located in the main ign. harness
Second Accesory = White/red located in the main ign. harness

Those wires can be used for turbo timers, radar detector wiring, extra accesories, etc. These wires are a heavy gauge and carry alot of current. Use these to get power instead of behind the radio. Fuse ALL accesories.

Power lock = white/blue = negative trigger = driver kick panel, in the door harness

Power unlock = white/green = negative trigger = driver kick panel, in the door harness

Use these for keyless entry and alarm lock wires. Make sure you test these. The door harness is large and white with several other wires in it.

Parking lights can be either negative OR positive trigger.

blue = negative trigger = that can be at the switch or factory alarm plug
red/black = positive trigger= back of fuse box, in the top and in the middle

Either one works, just read your alarm install manual and see which one it uses.

The door triggers are ALL found at the green alarm plug up above the driver kick panel.

Green = driver door = negative
Light green/red = passenger door = negative
Red= hatch = negative

You will need to diode isolate the door triggers. This keeps the door triggers from "sensing" each other. Put a diode on the factory wire and put the "stripe" side to the "car" side, not the alarm side. When doing this, it's very clear.

If doing a remote start on our car (it is possible with certain alarms) it needs a tach wire. You can also use this for larger ricer tachometers.

Blue = tach = in a two pin wire next to the battery.

White/black = brake = Positive = found at foot brake switch

Green/red = parking brake = negative = found at the green immobilizer plug in steering column (pin 4)

If you're adding a navigation unit and need the VSS (vehicle speed sense), it's real easy.

Blue/white = vss = cruise control module under dash. Left of the steering column.

I'll probably add more as people ask for ones I'm sure I've forgotten.
