ford fiesta 2000 uk w reg alarm wiring

Hey everyone, installed an alarm a few months back and still in the progress of installing it. The alarm system is a Cobra (7910 series) and I've installed everything I want on it apart from the remote lock/unlock feature. I know the car is a positive lock system and I've wired up to the correct lock/unlock wires in the driver-side kick panel but all that would happen is the car would lock when I disarm and do nothing when I arm. The alarm has three wires in the door lock loom: lock, unlock and what could only be a positive 12v. The instruction also state that there is no need for fuses. Tried wiring up a relay system as per the diagram on this site but with the positive 12v for the relays going to the alarm's 12v positive door supply, which is subsequently going to a permanent live 12v + at the fuse loom. Sadly, no activity from the doors at all with the relays. Can anyone point my in the right direction? So far, I've seen plenty for wiring up a two wire door lock alarm but nothing for one with a positive wire as well and I'm at my wits end with this.

What are the lock wire colours of the Cobra? Two types, earlier had ORANGE / white, violet/white. Later versions violet/orange. Then common, violet, orange, grey/black and yellow black. Early version, tie the ORANGE / white and the violet/white to the vehicle red. Later version, tie the violet/orange to the vehicles red. Then violet to either yellow/black or yellow/blue*. Then orange to either WHITE/ violet or WHITE/ green.* * Colour choices different vehicle batches. Quick and dirty test method: With only driver's door open, remove key from ignition and throw over latch at rear of door. Connect the red to each cable in turn, that should lock and unlock (or vice versa) in turn. If t5hat works and the alarm doesn't, recheck your wiring, also see if your getting 12V+_ on lock from the violet and 12v+ on unlock from the orange.

There's a violet (lock), orange (unlock) and a violet/orange (12v +). I had it wired as this: Violet from alarm to WHITE/ green on car (lock) Orange from alarm to yellow/blue on car (unlock) ORANGE / violet to a fused permanent live 12v + on the car As a result of this I got lock on disarm and nothing on arm. Tried the relay, as I said, with the wires to the correct pins and with the 12v + for the relay coming from the alarm's 12v + (ORANGE / violet).

What relay? None needed, the alarm has direct relay driven outputs. Also I think you might have the car colours the wrong way round, that's why you're getting lock on disarm. Yellow/blue is lock and WHITE/ green unlock. do as I said before about testing, unless you're using rubbish connectors like scotchlocks.

They're normal large green Ford relays. Dunno if they're the same in the States but the late '90s/early '00s Fords in Europe use them. Before wiring the relays I did try the lock/unlock wires the other way around but then I got no activity from the doors. I could of course try that way around again.

That model was never sold in the US, only the 78 Mkl and the current version, don't try and lecture me, I've done literally 100's of these vehicles, never any problems, go directly to the driver's kick well and pick up that wiring where it enters the car, forget the relays. Easy enough and if you follow the vertical loom in the kick panel you will pick up the indicators, blue and blue red. All door trigger at the light or left hand side. Try paying attention, I'm posting from the UK!! Used to take me 3 hours for a Cat 1, inc. bonnet and hatch triggers and boot release.

I wasn't aware I tried to lecture you. I referenced to the States as most on this site seem to be from there, not to mention that Ford is an American company. I'm not an idiot, I found the two wires just fine and I'm saying that wired one way, nothing happens, and wired the other way, the way I have been told elsewhere, just give locking of disarm and nothing else. I'm an adult, you're an adult...please communicate to me like one.

Also, pretty sure it isn't a blue and blue/red pair of wires, it's WHITE/ green and yellow/blue.

I wasn't lecturing you I was telling you! I'll repeat for your benefit what I said before. Yellow/blue = + unlock WHITE/ Green = + lock. Test by throwing over the door lock catch and joining each to the red in that loom. If that works you've either wired it wrong or the alarm is at fault (frankly unlikely rock solid build quality if rather basic). Test the alarm's outputs on the violet and orange wires when you arm and disarm the alarm. Incidentally don't connect the grey/black or BLACK / YELLOW to anything. Forget the relays you mentioned, irrelevant. Incidentally both DEI (Directechs)and Cobra and my memory tell me blue and blue/red but you may be correct, the loom may have come from an earlier year, between 94 and 05 they changed their wiring colours about 4 times.

You said I was trying to lecture you, not the other way around?! I'll tell you something, there is no red wire, so why keep saying to throw the lock catch (whatever that's supposed to mean) and test each one on the red wire?! On the alarm locking loom there an ORANGE / violet, orange and a violet and on the car there's WHITE/ green and yellow/blue...no red there at all.
