I have fitted a Scorpion car alarm to my wifes 01 fiesta 1.25 (old shape) everything is working fine except I can't get my head around the central locking.
Behind the drivers kickplate is a bunch of wires coming out the door, on testing there is a white/green and a orange/blue, the first wire is live and the second ground when door locks open. they change polarity when door is locked. I just cant get my head around how to wire up. I tried testing by putting a ground wire to each in turn, that just blows the fuse!!!!
any help or advice greatly appreciated!!
