thats a veryyyy broad question, basicly your asking for a member to write a 2 page essay, most likley along with pictures. without by the siounds of it trying yourself first. and not making a post in the welcome section?
Well if it was nicked then chances are it would be wired up anyway. I owned many stolen recovered from the police. They have tags on handle bars for the force's county they are from.
@OP Get yourself a new loom (If its legit you will pay for one) Or get a wiring diagram
