Hmmm
I i have been tearing through the fuse box and relays. I have disconnected the one working horn to listen for the relay. I can hear it and if i pull the 10amp fuse for the horn it does stop the relay. the weird part is I CAN NOT Find the relay! i pulled every relay in the fuse box and pushed the horn pad and i keep hearing it. how ever after the last post i wonder if this 4runner was only equipped with this little horn by itself? time for another upgrade!!
The horn fuse and relay (as well as three other fuse/relays) are located in the "integrated relay" module also known as Unit K and stamped “K”in the engine fuse box.
If you press the horn button and it blows, it’s all working OK.
If you want a different or louder sound you’ll need an after market horn or multiple horns. Search the forum for other early 5th Gen horn mods.
Yeah after all the searching, cross referencing, wire diagrams and a call to the parts dept. my 4runner just has one pathetic little horn. So my next question ElectroBoy, the pic you posted earlier, is that a stock pic behind the grill or your 4runner? if so can you tell me if both of those horn use one plug? or do they each have their own? i guess i can pull the cover off the wife's 2019 and look. but yes ill be getting a newer horn soon. this thing is pitiful!
Thanks everyone for their input, advice and help. i guess the bright side is i have a newer clock spring that I didn't need! LOL

Just a note.
Adding a horn is easily doable and should not cause any issues.
I had a 2013 FJC, it came with 1 horn, yep....that's right a 2013 FJC with one horn.
I looked up the part number of the OEM horn and ordered a mate for it. Made a split jumper and eureaka.... a much better horn tone!

OP, did you see this thread?
New Fiamm Horn Install
At some point they went to two horns in front. Soon after the 5th Gen intro. If you look back there were a few threads about replacing the horn(s) since they were so pathetic.
