I am putting all new wiring on a 1970 WH Raider 10 with a Tecumseh HH100. The only question I have right now is the wiring diagram shows a black wire from letter M on the ignition switch going around the front of the engine but doesn't say what or how it connects. Any help is appreciated.
FYI....the old setup had no such connection but also would not shut off the engine with the key switch.......related?
