Tried to search the threads, no luck...there has to be a relay somewhere. Does anyone have a wiring diagram? I checked the block up in the front left of the engine there's a 10 amp fuse that runs the hazard and Horn. I checked the block drivers under dash, no relay. There's a block behind the kick panel bottom left drives.

I had to fix the thing behind the steering wheel... After all this mess I'm just going to replace the horn, mine is original and kind of anemic. Hobo freight has a nice set for 10 bucks comes with a relay. I don't want to wire the relay in if I can find mine but I can't find it.

Thanks!

 

you can't find it, because there isn't one. toyota did not use one in the '86 4runner.

 

I have a regular 2x4.... tks

 

Like Wally says, there is no relay on the 1986 to 1988. I don't know when they added the relay.
Here's how to troubleshoot horn:
