1992 pontiac sunbird - is the horn supposed to have one wire or two wires connecting to it?
Please provide more info. Do you mean the horn itself or the actuator on the steering wheel? In either case, I believe the answer is 2 since all electrical devices in the car need to have a ground connection and most things, like the horn, run through your main breaker panel. I hope this helps, but if not tell us more about your problem and maybe one of us can help.
in the steering wheel there is only one wire because the body of the car is grounded. but the horn under the hood i think has two wires.
