Nice write up swiss, do you know if the stock horns run off a relay? Most aftermarket horns either come with a relay or recomend that one be used.
Thanks

Yes, there is a factory horn relay and I did not change that.
I took the new relay out of the kit and will save it for some other project.

Here is a write up I did a while ago on this.

Nice job swiss!!

I bought a set off of E-Bay and I installed them today. It was simple and effective - these horns are much louder. And as an added benefit, my car alarm is super loud now!

Just out of curiosity.. For me and those who aren't concerned with the horn being too loud.

Will the HL85115 Supertone horn kit work as well, given the same instructions and parts.. aside from the fuses? I mean.. I would like to be downright obnoxious- on top of being able to attract the attention of fellow FJ owners, naturally.

Thanks Swiss. After reading what you wrote, I went outside to honk the NEW FJ'S horn (what a wimpy sounding note, wonder if another car could hear it in an emergency?). I too ordered them. I did not install them myself (I only know where the gas and oil go). Had the FJ in the shop so they could install a heavy duty transmission cooler with a fan. Since they would have to have the bumper and grill off, just let them install the horns. All I can say after honking the new horn is SWEEEEET. Now that is a REAL sounding horn, not something that belongs on kids big wheel. It will get someones attention in an emergency honk.
Again Swiss, thanks. Never even thought to test the stock horn since driving off the car lot.

They should work just fine. The mounting will be a little different due to the shape and size of the horn, but it should not be any issue.

I was told those are the same horns they use as sirens in Germany. Give us a report on those after they are installed ... they should be bad!

Swiss, thx for the step by step. I did the PIAA's and they are great (and you can hardly see them). Awesome post! K

I installed the PIAA horns too. Just installed the right horn where the OEM horn is attached, hot wired each horn to the single horn wire with a quick connect, and, after sanding away some paint to allow contact, grounded both horns behind the bolt attaching the left horn to the metal bar through an existing hole, and was able to hide all of wires covered with wire wrap under the metal bar using only one zip tie and some electrical tape. A very clean install w/o any exposed wires, except the hot & ground wires plugged directly into each of the horns. No extra relay required and all you can see are the shiny labels on the horns through the grill, which looks pretty cool! Sounds great as well at 115db!
