The horn relay on my 86 was taped to the wiring harness on top of the fuse panel.

location and wiring of the horn relay
I though this would be easy since my horn still works-- so I opened my 89 Wagoneer's hood and looked and looked-- and looked some more, but never found the horn either. I DID find the horn relay (I think) behind the head light assembly on the drivers side. If you find your horn and have a minute or two please let me know at tjuul02@yahoo.com I did however recently order a new CHILTON repair manual from Rockauto.com so maybe in a few days I'll know much more than I do now about many things on this Wagoneer.
The horn relay is mounted behind the instrument cluster display. This display is the one that has the overdrive, parking brake, security, service engine soon, etc. readouts.
On the steering wheel
If you are refering to the belt tensioner. I have not seen one on a grand wagoneer with a 360.
There is no relay for the horn!
There are two simple answers 1. the wire has come loose from the horn located near the radiator. 2. the wire has come loose from the horn button on the steering wheel. If these are not the cause than there is likely a broken or corroded wire. The grand wagoneer is notorious for corrosion and i am guessing the wagoneer is the same. good luck.
where is Horn relay on 1996 buick century.??
There is no horn relay on a 1970 mustang
Basically, a "relay" is a switch. When you push the horn button you're triggering the relay which in turn feeds power to the horn.
Most horn buttons provide the ground to energize the horn relay. The horn relay when triggered sends power to the horn.
