I'm helping a friend with a '75 R90/6. Been sitting for 25 years. Had a Vetter fairing we removed. As many of you know, the fairing wiring required some considerable mods to the factory wiring. I think I have most of it figured out and done. But, of course, a couple of questions: we had to get a replacement ignition switch and the back terminals are labeled 58/30/15 across and the diagonal is #56. I've got the gray and red wires nailed down as #58 and #30. But I think 2 greens go on the other two, but what ones? I have a double green that has a bare connector on one end, and a single green left. Of the three connectors left, I'm sure one goes to the 'board' green, one to the #15 and one to #56. Just don't know which one. I see photos of switches with the #15 and #56 reversed marked as well. Hope I have the correct configuration switch for '75! Any help appreciated!

Update

I think I have the switch wires sorted. Power to dash, clock. Found the headlight switch faulty, can be fixed I think, and that brake fluid had cooked the 4-way flasher and starter relay. Starter also bad, turned briefly with screwdriver method, then dead. Removed and jumped directly from battery - dead. So more electrical work ahead. Good news is the front brake is as new, $350 later and the carbs are rebuilt in excellent shape!
