Hi , no there is f/c alarm just the standard ford job at the mo, its a k reg so no immobiliser, have been wondering if at some point some one had one fitted or a remote start alarm as all ign wires have been spliced into !
will chase the window loom and chack it for any splicing/bad joints !
just seems funny that it dont blow a fuse when the live wire connects to the earth ! will play some more and let you know how it goes.

cheers !
