Re: Horn wiring
On my 70 El Camino, those wires connect to the horn button assembly under each horn button. If you ground those wires, the horn will make horn noises. Pushing either horn button (if equipped with two) is the same as grounding those wires.
There should be a connector near the turn signal switch area to connect the other end.
