Hi Guy I am sure you have your wiring problems sorted out by now. But just in case ebay has harnesses plus any US bike wrecker will have dozens of these. I have seen some full colour schematics offered on ebay but I think I would send $25 and ask a wercker to chop out the section you need and use it as a template. Let me know how you are making out and where you are located. I am In British Columbia and just bought an 81 midnight special... I suppose I could take my covers off and see if I could help. Ray
