Hi Martin, to be honest you've added your question to a thread that's been dead over 7 years!

I personally was never an expert in the first place, but as I started the tread, I get your "reply" notifications and thought as a courtesy I'd let you know how I (didn't) get on.

I do know Its frustrating working with limited information available, but maybe take care not to let that show in your thread responses?

At the time I did find some wiring diagrams somewhere on the internet (they're probably still be out there somewhere). I printed
them on A3 paper and spend lots of time with a multimeter and pin probes etc. Ford tried twice to get me the right replacement loom and in the end they gave up and refunded the purchase (but sadly not my time or effort).

FYI The diagrams I found were for a later model, but the wire colours and pin numbers hadn't changed.

Once I found those wiring diagrams, I could then see what relays and fuses were fed from where and then went through each circuit methodically and individually - I'm a very patient person!

After all this time, especially since I don't normally work on Ford Cars, I really cant remember anything specific to help guide you today - sorry.
