Found mine

I'll try to take a picture of it tonight. I'm not sure if it is in the stock location and somewhere along the line the factory harness/connector went bye-bye and female connectors were spliced on but it is there.

Mine is located on the top of the PS inner fender, bolted to a welded nut on the fender. Just rear of what would be the middle of the fender and it looks like this or this or this but without any stickers/markings other than the stamped B, H, and S as seen in the first link.

From the electrical diagram posted by Coolerman (here) the two horns are spliced together and connect to the "H" on the relay, power comes from the fuse block and connects to the "B" on the relay, and then a wire runs from the horn button itself and connects to the "S" on the relay.

Mine looks a little "weathered" but I haven't had a chance to test it. I'll try to clean it up and see what happens. If that doesn't work then I may just buy a new one and be done with it. Need to call Burt and see if they carry the item or if they can get it or add it to the growing list of stuff to order from CDan.

Here are some pics from my 12/74 FJ40. Horn relay is OEM, probably original, and as far as I can tell it is sitting in the stock location (based on SORs drawing). Sits a little further back than I first remembered. I think I'm just going to see if I can find an aftermarket relay and see if my horns will start working again. I did spend about 15 mins cleaning up this one and still nothing but a weak "brrrrrrrp"

Thanks for the photos. I'm convinced my stock '78 is relay-free, regardless of SOR and other showing fitment from '69-'80.

Steve,

It seems to be that if your horns have two wires going to them then you don't need the relay

Forgot to follow up on this...

I replaced the horn relay (with a new OEM unit from CDan) and my horns work perfectly now - Occassionally I could get them to work with the old relay, but it like 1% of the time. I thought about taking the old relay apart to see if I can clean it up and get it to work...Probably never will though...

So, if one day your horns just go "brrrrrrp", and you have a relay, that is probably the issue - Oh, and new OEM was cheaper than aftermarket IIRC

Default horn woes....

Hi,
I have the opposite problem on my 76 FJ40. After an inadvertent short from ammeter wiring in dash while replacing a brake light switch, I toasted some wiring :-(( Now my horn wont stop honking!

I did find some heat damaged insulation on wires to ammeter and spliced in new connections. Everything else works, but had to disconnect the wires to horns. I looked at wires coming from horn switch on column and no siges of any heat damage. Previous owner had installed an alarm system, so wiring under dash is a rats nest. Could a faulty horn relay or wiring at the relay cause the horn to continuously honk? I am an electrical novice, but trying to figure this out!!!

thanks

Anyone know where to get a nice clean horn button for the steering wheel? a 72 model?

Did you check the horn button contacts themselves as well as the wiring in that area to make sure one of the wires isn't grounded out? As for if the relay could be causing the problem I would guess it could. A new OEM relay is relatively cheap IIRC and worth a shot.
