I also have a black wire coming from the ignition switch for my 82 S10 column. Any idea what this is for? I am putting the column in a 49 Chevy Pickup and am doing the wiring myself.

Thanks...

Ground most likely.

Yes black usually indicates a ground wire.

makes sense to me....thanks

hey i have a 98 chevy s-10 i had to take the dashboard out because i snapped the plastic pivot for the clutch pedal anyways everything went smoothly back into place but i have a plug that dosnt have a home i work for a nissan dealership and by no means am i stupid.
