I need to rewire my horn and it's the last thing electrical to do. What is the Horn relay on the firewall for? Is it for the use of more than one horn? My truck has two.

Hi neigbor. Yes it probably is there for 2 horns. The standard 1 horn on that model doesn't use a relay although it's a good idea to put one on. It should have a 10-12 gauge wire from the bat or junction going to the B term.on the relay. It should have a equally heavy gauge wire from the H term to the horns. The S term is hooked to the botton in the steering column. It can be small gauge wire. If you need help E-mail me & I might be able to swing by & take a look.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.

And, only one relay would be sufficient for the accessory dual horns.

Thanks, I was only planning to use one horn. Just to clarify, if I'm only using one horn then I don't need the relay?

I have no Idea what style horn it is. They are not original to the truck.
