Hi guys I bought a fait marea a couple of months back and really love it, I cant believe that you can buy a x reg car with 30k on the clock for little over a grand.
Any way the one thing that has annoyed me is the lack of remote control locking , so I bought a kit and just cant get the dam thing to work
The alarm side of things works fine, but the central locking is a bi*ch.
I found the blue and white wires that every one on here talks about (im guessing they mean the turquoise blue wire that splits into two, and the thin plain white wire not the thick gray one.) any way I wired the kits loom so as it responds to a negative trigger like the wiring manual says and when I tell it to lock I get nothing. I can hear the relays inside the unit going crazy but the locking just dost lock, if I short circuit the two wires (as I described above) the locking, locks but then immediately unlocks, even if im sitting in the car with all the doors closed, this even happens if I just tap the wires together for less the a second. But I get the same effect if I just tap the blue wire against the body work. Which makes me think that im using the wrong wires especially the white one as this must just be a negative wire, I tried the gray one but still I got nothing.
I thought it must be a problem with the unit so I took it back to the shop and tried a further 2 units and they all did the same thing.

Any one got any ideas’. Im happy to post the relay theory diagrams and pictures of the two locking wires im using if that helps any one.
Thanks for your time.
 
sounds like you're using the actual lock and unlock wires, rather than the lock/unlock signal wires for the relay.

when i fitted remote central locking to a bravo i removed the glovebox and then used the yellow central locking relay to identify the correct signal wires.

i would also check that the wires on the central locking controller are actually earthing for a second when you press the remote (check with multimeter) just to make sure you've got it set to negatively switched mode.
