Steering column horn wiring diagram need. horn sounds when the steering wheel is turned. 1982 was as far back as the years went on the selection, I do need 1972.
Did that, did not fix the problem. the small spring that depresses when you press the horn ring may need to be replaced and/or shorting out. Impossible to find the part needed.Did that, did not fix the problem. the small spring that depresses when you press the horn ring may need to be replaced and/or shorting out.

You will need a wiring diagram but test the power to the column multi plug to see if power is available. Then carefully ground that wire and see if the horn sounds. The horn contact is basically a brass ring and a sliding contact to allow the passage of current as the wheel is turned. Operating the horn is just grounding the supply via the ring. It works off the FOB by a separate relay triggered by the signal.
Could be a short in the steering wheel or column. Or a faulty horn relay. You may need a wiring diagram to trace the circuits from the relay. Usually the black wire is the ground and the green is voltage from the relay.
is your horn relay good, swap another relay and see if that works, if not you should check wiring at lower steering column, you could splice wire from relay to wiring harnees at lower steering column inside vehicle
there is no relay for the brakes but there is separate flasher for the signals. Your problem is more likely a wiring or switch issue, as these systems use the same bulbs. Check the wiring at the back of the truck. If someone put a trailer connection in there, that might be the problem. If not, the stop light wires go up the steering column to the turn switch and then back down to the lights. I have pasted your wiring diagram below and also instructions for getting to the switch in the steering column. This requires a couple special tools that you may be able to rent or borrow. Sorry this is not good news...
Turn switch access:
Disconnect the negative battery cable.
Remove the steering column trim.
Remove the horn pad from the steering wheel.
Remove the steering wheel and horn collar.
Use a suitable puller to remove the steering wheel.
With a suitable compressor, compress the preload spring to the lock plate. Compress the spring only enough to remove the snap ring.
Use a pick and a small flat blade screwdriver to remove the snap ring.
Remove the lock plate, horn contact carrier, and spring.
Remove the bolts at the upper steering column support and the upper mounting bracket from the column.
Disconnect the turn signal wiring connector.
Wrap tape around the wire and connector.
Remove the hazard warning knob from the column.
Remove the switch retaining screws and remove the switch.
The horn relay might have welded contacts (stuck in the on position). Pulling the relay should stop the horn.
The wiring harness on the steering column might have a broken wire to the horn relay shorting to someplace that applies power to the relay. In this case, turning the steering wheel all the way to one side or the other may stop the horn, and it won't sound when you press the horn button.
The horn button in the steering wheel is stuck on or shorted.
You missed something putting the column back together. IDK the design of the wheel, but if all the wires to the column are good, I'd look at the switch itself in the column. Probably not making contact.
a 1965 camino,centre steering wheel horn push? remove the steering wheel and check the carbon brush that runs against the copper metal ring on the bottom of the steering wheel
Position inflator module to gain access to wire connectors. Note wire routing for assembly reference.
Push in and rotate horn contact lead counterclockwise, and remove from the steering column horn tower.
Horn contact lead.
Retainer (CPA) from SIR wiring connector.
SIR wiring connector from inflater module.
On models so equipped, disconnect steering wheel control switch connector.
Inflater module. WARNING: When carrying a live inflator module, make sure bag and trim cover are pointed away from body. Never carry the Inflator module by wires or connector on underside of module. In case of an accidental deployment, bag will then deploy with minimal chance of injury. When placing a live inflator module on a bench or other surface, always face the bag and trim cover away from surface. Never rest a steering column on the steering wheel with inflator module face down and column vertical. This is necessary so that a free space is provided to allow air bag to expand in the unlikely event of accidental deployment. Otherwise personal injury may result.
you need to Check the Wire inside the Steering wheel, When Grounded by pressing horn button the relay will send the 12 volts to Horn,
You Also could and Please Re-check the Color of wire for the Horn SHOULD be a Black Wire in the wire loom Under the Dash on the Column and If you Ground down the Black wire from Under the dash, You would Find out If it is In fact the Steering wheel it self,
you could also add a Second Button on the Dashboard
