Re: 67 starter wiring question
Yellow wire is coming from the ballast resistor. If you are running an after market ignition, ie MSD you dont need this wire.
If you are running a stock ignition, coil and distributor then the ballast resistor is a porcelin fixture with a wire in it. It should go pink 12V ignition wire to ballast resistor, yellow wire from the BR to the solenoid (R). A wire should also come from the downstream side of the BR and go to the + coil.
The red wire is a 12V battery wire. Goes to the battery post on the solenoid.
