Help me understand the route that the wires should go from power source to the horn. Someone has put a ground in the steering column with one wire positive to ground there to blow horn. I’m thinking the positive power side runs thru the column to the horn with the ground there at the horn. Please clarify.
if you have speed control, there is a horn relay...grounding the wire at the horn switch causes the relay to close and send power to the horn(s). The relay is located on/around the speed control amplifier under the dash...
I did have speed control but removed it years ago. Not sure what was left under dash. What’s confusing me is the two spring loaded wires in the column. One is hot and activates the horn when connected to the ground. The other wire is dead, and not sure where it goes, was it always dead? More investigation needed I’m sure.
Well that looks like a aftermarket (Grant?) steering wheel adapter, so you might have to get creative with the horn wiring. Usually on a OEM set up, one wire it hot and one is gnd with a U shaped push in clip.
Dlburch and 77&79F250 were correct, had to get creative with wiring as I did have speed control and the relay was remove during restoration. All good now, loud and clear. Thanks for the good info.
What did you end up doing? Creative is good, but details are even better if someone else has to do it in the future!
I would have initially said that your turn signal switch with the two horn contacts was for a non-relay setup. But I guess the pickups were different than the other rigs, where the relay trucks had only one horn contact under the wheel. Touched to ground, the horn would honk.
The non-relay trucks had two contacts. Power in from the harness, and power out to the horn. The horn button simply connected the two when pushed.
Interesting setup you have.
