hi folks this is a shot in the dark really but was going to connect my head unit this weekend but the wires coming up from various places has no connector block on the end. Basicly the previous owner didnt have one fitted and now there is a mess of wire in the place where head unit should be. I.ve brought the ford adapter so head unit is ready to go but wires the other end arent. Is there anyway of identifying what colour wires do what and where they should be attached? Hope that made some sense. Cheers luke
