I'm trying to wire in keyless entry to my Focus, with no sucess.

I have found two wires in the GEM that idle at 12V and drops to 0V for half a second when i lock/unlock the car. My GEM has one plug with 16 pins, two rows of 8, but not wires in every pin. The cables i found were in pin 1 and 2 and had the colors Yellow/Black and WHITE/ Black.

The kit i am using is a KE60W-Plus. I have wired it up according to the installation manual for negative trigger locks. I have checked my module in a friends car with the same keyless entry kit, so i know its working. But just can't get it working in my car.

Any ideas to what i can do?

My car is a 99 Ford Focus ZX5

You have found the motor wires rather than the trigger wires. Trigger wires are ORANGE / black lock and green /black unlock both neg going. If your key less entry system is relay driven, i.e. 6 lock/unlock wires set for neg going and join. If it only has two lock output wires, set for neg and diode the wires (1N4002 etc) with the bands towards the key less entry.

Here is the wiring diagram for my keyless entry kit. As you can see there are two lock/unlock wires, so i guess it's not relay driven.

So the wires i found were power wires to the motor? How come they jump from 12V to 0V to 12V in half a second when i lock/unlock the car? I have found so many diagrams over what colour the the triger wires are that its confusing. I according to https://www.the12volt.com/installbay/alarmdetail/882.html the wires are BLACK/ Orange and BLACK / YELLOW and in the drivers side kick panel. I tried probing all BLACK/ Orange and BLACK / YELLOW wires i found, but didn't see any change when i locked the car.

The triger wires, are they at in the GEM plug aswell? What should i look for in the wires? Are they resting at positive voltage, then puls to negative when i lock/unlock the car?

If it makes any difference, i have a norwegian Focus.

I just found a wiring schema for central locking in Ford Technical Information System, and it seems like you are right. I will wiring it up tomorrow.

That diagramme is correct, I got my colours wrong way, they're ORANGE / black and GREEN/ black. In a Norwegian spec, GEM box should be against inside right front wheel arch behind glovebox. Your unit does have relay outputs because it DOES show 6 wire set up. Don't use orange or ORANGE / black, white to ORANGE / black of car and WHITE/ black to GREEN/ black of car; take yellow and yellow/black to ground. The wires you originally found sit on ground then on lock yellow black goes live whilst WHITE/ black stays on ground whilst the reverse happens on unlock. Some versions of Focus have deadlock and this would be plain yellow. First two go live for under 1 second, yellow goes live for 2-3 seconds to deadlock vehicle.
