ford fiesta 2000 uk w reg alarm wiring

Sorry the "red" wire is either ORANGE / black or ORANGE / blue. More colour changes.

Ok, I'll try the lock/unlock wires the other way around tomorrow again and report back.

Still the same situation as before...lock on disarm and nothing with arm and when I tried the wires the other way around then nothing happens at all.

Have you even bothered to test the alarm's outputs or those wires yet?

Not without a multimeter I haven't, no. Regardless, to me it looks like the wiring is the issue and not power coming to and from the alarm unit. Any other thoughts on this? I will, of course, get the wires tested ASAP in the meantime.

Test the Cobra's violet wire. No point talking about it. If no output the unit's faulty, if there is an output you've done something wrong.

So, care to point out what I've done wrong?

No* but let's take this from the top.... Open the driver's door only. Now use the lever on the inside handle and try and lock it. It should lock then unlock. Now take the catch at the rear of the door and with a screwdriver, flick it over. Now if you use that inside handle it should lock and stay locked. (All European cars have an interlock safety mechanism to prevent the vehicle being locked by mistake when you just want to shut the door). Now go to your chosen lock and unlock trigger wires. (Called that because they trigger the existing relays). Touch each in turn for a second with a piece of wire lock first to a 12v+ constant, such as a fuse in the adjacent fuse box. The worst case if your selection is wrong is a blown fuse. If that does the lock and unlock proceed to the alarm itself. With either a DMM, a test light or a 12v bulb with 2 bits of wire joined...it really doesn't matter which, arm the alarm. The violet (purple) wire should show 12v+, the orange wire nothing. Now disarm the alarm, this time the orange wire should show 12v+, the violet nothing. That's it. No* because I haven't a clue as to what you've done.

Ok, I'll give those steps a shot. Basically, all I've done in terms of remote locking is that I've wired the three wires up...the lock, unlock and 12v+. There's certainly power going as I've said before but it seems to be messed up somewhere or I'm missing something. In the alarm's door lock loom there's two other wires but the instructions say to only use the three I'm using if the car uses a positive lock system.

And yes I already mentioned them, grey/black and yellow/black, insulate them off unused. I should have mentioned the last phrase before though.
