I have a 1972 20hp johnson, with electric start and choke. The problem is that the female end that plugs onto the motor is all weathered and cracking. My question is can I just get that plug end with like pigtales on it and splice it on? I don't think the wires come out because it looks like the wires are molded into the rubber plug, but the wires are bad right where the wires come out of the plug. So do they make such a thing without buying the whole new wiring harness? Does anyone happen to have one?
