I just put a painless universal 12 circuit in. My first complete rewire job. It was really nice. They were color coded, sectioned, numbered and labled. I had to cap off half a dozen such as 4x4 indicator,elect. choke, cooling fan, a/c compressor, ect. I took my time and went slow and when I turned it on everything worked. I called the tec. line once and they answered my question and faxed me a seperate diagram.
