First of all, I have done several searches on horn relay wiring, and all the topics/diagrams I found were very helpful. With my car, it looks like the previous owner jacked up the harness to remove the external regulator. My horn relay has all the correct wires going into it except the wire from the steering wheel. I have the hot lead from the battery, the pink wire for dome light??, and the black wire going to the actual horns. AND, I have pulled off my steering cover and I can see the horn wire connected. It has terminal connector and then the wire feeds into that black plastic tube down into the column. My question is - where do I go from there. I keep reading that it attaches to the steering column or shaft somehow, but is there then a wire that comes from the shaft into the horn relay? Should I have one single wire from the horn pad to the relay, or does the steering shaft serve as part of the ground for the circuit? Help!
