Bit of a long shot but does anyone have a ford immobiliser wiring plug? (Green 4 pin type). Searching ebay etc the whole aerial units are going for £20-£30 (and mostly from Lithuania!?), I just need the connector though. Will keep trawling the internet in the meantime. Cheers!

Oddly enough, I was looking for exactly the same thing a couple of weeks ago, and couldn't find one either.

Went to my local scrappy, and he found one within 5 mins - no charge! Since these were fitted to a lot of Ford models, that may be your best route, too.
Failing that, you can try the bloke I went to... Norfolk Salvage 01603 881024

HTH

Cheers! Yep I think that may be the way to go now. It's not urgent, I've bodged it for now but would be nice to have it wired up correctly
