Hi.I think I've got the engine room wiring almost figured out(maybe).A big mystery remains a three lead cable that leaves the harness about the top,middle(12'oclock position)and heads down the middle of the motor towards the bumper(until it gets to where the P.O. cut it off,grrr)I think one of the wires is red.Could this be for the dual carb's choke and idle cut-off power?
