Re: 69 gmc needs started no spark
Jofin66GTO, the pink wire from the top of the HEI cap does not go to the ignition switch. It goes to the unfused ignition terminal on the fuse block inside of the cab.
The purple wire goes to the ignition switch. If you have a neutral safety switch on the topside, bottom portion of the steering column, then the purple wire connects to that. I can't recall howmany terminals are on the neutral safety switch, but two of them are for the purple wires. One of the purple wires comes from the starter solenoid and the other one comes from the ignition switch. If you don't have a neutral safety switch, then the purple wire goes from the S terminal on the starter solenoid to the ignition switch.
I hope that makes more sense.
