Help, I can't find the horn relay for a 79 C10 that I am working on.

Re: Horn Relay

Hi Charles,

The horn relay in your '79 should be located along next to the wiring harness above the fuse box. It'll likely have a cube shaped plastic housing and might be taped to the harness or just hanging free from it's wires/socket.

Re: Horn Relay

Ditto. It's a plastic box that doesn't really look like what your expecting it to look like.

Re: Horn Relay

Thanks guys, it was taped to the wiring harness and tucked behind the fuse box. It is a small square plastic relay and it was bad, so replacing it fixed the horn. Ya'll rock....
