Strange horn issues
I finally decided to try and tackle my horn issue. What i discovered was that the male spade connectors on the steering wheel do nothing when jumped. If i ground the powered connector to the frame of the wheel the horn sounds but only if the key is in the off or acc position. Any ideas here?

No cruise control. If i am right then the horn button just grounds out the power wire for the horn, causing it to sound. I clearly have a ground wire issue, but i dont know what would cause the power to reach the spade connector only when the horn is in the off or acc position

See if this helps, it's from the 1981 EVTM but I believe the wiring is the same for yours.

Just got done reading a post that had my symptoms with the connector only getting power with the key in the off or acc position. The coupler on the steering shaft that attaches to the rag joint is broke, so im off to the jumkyard this weekend to get a new steering shaft. Now i just need to find the issue with the negative connector not grounding.

If you don't have cruise, the circuit grounds at the horn. Look at the schematic ctubutis has in his post. There should be two wires at the wheel to complete the circuit.
If you have cruise, there is a horn relay as the circuit is low amperage because of the cruise. Then you would ground the wire at the wheel.
Because you don't have cruise, I'd check voltage at the horn and work your way back, wheel, wire going to horn, then wire coming from fuse box. Check the fuse first. Does the cigar lighter work? If not, it's more than likely the fuse, then also check to make sure there's no change that was dropped in the cigar lighter as it's on the same citcuit (you wouldn't believe how many times I've seen that).
