Re: 1970 GMC steering column wiring harness mount
The Turn Signal Switch harness plug runs from under the steering wheel, down thru the column, and connects to a similar curved connection -- usually under the dash near the Light switch. This is for the horn, turn signals, hazard flashers etc.
The bundle should go into the Fuse block.
