When I bought the truck the horn button was relocated to where you would find the volume button on the radio! As there was no radio present, this was a bandaid fix to the real problem. The horn contact switch had gone in the steering wheel. (I neglected to photo this repair – but will get some shots as I pull the truck apart)
There was also no relay for the horn. From what I’ve read, the relay was standard on all trucks. The lack of the relay is what likely melted the contact switch on the steering wheel. As the replacement horn contact switch looked very flimsy, a relay needed to be added. I could of bought a relay from many part places, but I happened to find an old GMC school bus at a wreckers. When I popped the hood, I saw the horn relay, and quick detached it! I had no idea if it worked, but what the hell – clean it up and give it a try.
The horn that was under the hood wasn’t the factory horn, the wiring harness suggested it originally had the bugle type horn which attached to the manifold. One of the Stovebolt members was parting out a truck, and I picked up one for $20. You can hear it in action!
Time to open it up and clean it up…
