Checking the coupling at the regulator I found continuity on all 3 wires (blk/grn/brwn). Unplugging the coupling for...

    Where does my clutch safety switch hookup to

    Hi, I recently built a 1981 Yamaha xs650s bobber and I cannot figure out for the life of me where the clutch safety switch hooks up to. There are no empty connectors anywhere. If someone could help I'd very much appreciate it. I also can't find it in my wiring diagram.
