I've been trying to locate the factory horn(s) on my '04 Ford F350. I want to tap into the wiring and add a louder horn to the system. Are they behind the fender liner on the passenger side or what?

Thanks,

John

Easy. Get your helper to stick his head in the engine bay and hit the horn. He'll tell you where it is.

on my 06 f350 the driver side one is under the battery tray and the pass side one is in the fenderwell and you gotta remove the fender well.

On one of the semis I used to drive I installed freight train horns with a custom bracket I made under the sleeper...yep...real loud! No more issues with people in my blind spot! Install youself a compressor and a some big rig air horns and bingo bango you have a real set of horns! That way you can install airbag suspension as well!

Tried that actually. It sounds like it's coming from the passenger side fender well.

I think that's where they might be too. Thanks for the complement on the Falcon. I have a few photos in the Garage section here too.

I'm actually doing something like that but with simi horns. I have an on-board compressor for my air bags that I'll probably be using.

It's a dually and we pull a 33' fifth wheel RV trailer. It's amazing how many people either don't see us or maybe don't care that we're 20,000 lbs rolling along the road and pull right out in front of us! This will help "remind" them we're there. ;)
