thanks alot all, where can i find the ford wiring diagrams?, probably me being stupid, but i cant seem to find them. Also, what you're all saying sounds like a good plan, ill keep the engine loom as one piece, and then work from there. At the moment im going through the haynes wiring diagrams highlighting all the wires and bits i do actually need, and hopefully i can put the rest together from that. What sort of a fusebox would i need to buy?
Also i don't have a huge amount of knowledge about sierra wiring, so ill probably be asking hundreds of wiring questions
Thanks
