When connecting a fuel pump using the old solenoid fuel valve electrical connection anyone got a clue as to which one is a ground?
Do not attempt a ground connection from the fuel solenoid wire bundle… Put electrical connector on a piece of 16-18ga black wire about 8-10 inches long and connect it to the frame with what ever bolt you use to firmly attach the pump. This is what “Patron Saint Paul” did for me on my bike. We mounted it under the Igniter, with a hand made mounting bracket from the igniter bracket, and put the RR on top or the Igniter, Horizontal and slightly inboard, with a hand made bracket.
