Hello, I am trying to repair a difficult starter problem and need to know the wiring color codes at the ignition switch. Mine stays running only when the switch is held to start. I put in a new switch but still have problem. I have a 1977 K10 4x4, this board is more active than truck board and since they are the same switches I posted here. My columm is non tilt, the tilt wheel switch works oposite mine. Thanks for help.
