Im guessing this is the factory fitted alarm for the RRC, mine is a 92 3.9 vogue se. Can anyone confirm how the wiring should be in the small plug on the harness please? I’m purely guessing at the moment as the fine wires had snapped. Does anyone know what these wires would do . They run to the back of the unit blue red and white wires. Many thanks

The look like the sort of wires that would go to an ultra sonic sensor(s)??
In which case it would be red positive, blue negative and white signal return.
If you power up the alarm, you can check for voltage on the pins with a DVM.

I believe you’re right, I managed to find out it’s a dealer fitted alarm system and was a £500 option in its day apparently. Anyway I’ve also managed to find out it’s a scorpion system and after hours of searching found a wiring diagram. I’ve got a bit of work to do before I can power it up to see if it works but either way it’s easy to bypass.
