I have had the same problem described here by a number of you. When I turn the steering wheel, the horn blows. Since I was traveling through the neighborhood when the problem started, I pulled over and disconnected the green wire to the horns on my 76 Corvette. After reading posts here, I learned that it would be advisable to disconnect the black wire into the relay so as to avoid draining the battery, and other electrical problems. I will delve into the actual horn problem when I replace the Vega steering wheel one of these days. So I have located the relay, hanging down behind the brake not far from the fuse box. But I can't seem to get the black wire to come out. It has been crimped into the connector, which in turn has been inserted into the relay. Using a pair of needle-nose pliars, I tried to pull the wire out, but it is not cooperating. I don't want to rip the wire from its connector. Any suggestions as to how to get the wire out of the relay? Is it just a tight fit? Do I just yank on the wire and hope it doesn't break from the connector it was crimped into?
Be very careful when removing the relay! It's in a stupid place and VERY firmly attached to the socket! Pull too hard and you'll damage the wiring harness. I know this because I found previous damage from someone yanking on the thing.
I'm back again. What I thought was the horn relay was something else. After reading on, I located the relay, the light blue, square inch box that is tucked up near the fuses. Since I am 64 and not a contortionist, I am not able to reach that damn thing with two hands. I will attempt to disconnect the black wire at the base of the steering column. What does a harmonic connector look like? All I can find are pictures of harmonicas, which doesn't do me a lot of good. Please be gentle, I'm mechanically challenged and learning this stuff on the fly.
Now you understand why I warned about yanking on the horn relay...
It's called the "harmonica connector" because it truly looks like a harmonica. It's long, flat and thin. Its clipped to the steering wheel column near the base on the right side. It's only slightly more easy to access than the horn relay
Frankly I'd remove the relay before removing a terminal from a connector (not too easy) or cutting a wire (never a good idea).
Any agile grandkids around?

The issue is in your horn circuit in the steering column the horn circuit is grounding out when you turn your steering wheel. Research on this forum to help fix the problem.

Removing the relay stops the horn from sounding until you can sort it out. Basically you can still drive your car. I'm with you on the horn contact grounding out.
I had an issue with the horn blowing when it wasn't supposed to.... I went through all the relay, pulling wires, replacing things. My issue was that I bolted the steering wheel to tight. If you have recently installed your steering wheel,,,, pull it off, reinstall it,, not so tight... An easy fix if it works.
Thanks for all your knowledge and advice. I think I will order a real Corvette three-spoke steering wheel and all the internal replacement parts and then tear into it. I don't know if I will attempt to screw that job up or have it done for me. Getting into uncharted territory here. Thanks again for your help.
