hi mate
im having one built by http://premierwiring.co.uk/ I was recommended by him from a few users on turbosport. its about a 3 weeks lead time and he is based in Spain now. but I have spoken to him on the phone and via email. he has explained everything along the way and from the pics I have seen on turbosport looks a quality bit of kit.
he leaves all the wires long so you just need to cut to size and fit the terminal, comes with fuse box, relays etc and everything is labelled up. and he uses ford diagram so wire colour is the same
