Hi! A previous owner deleted the horn on my '99. I tested the switch and the relay, that works, but I can't for the life of me find the wire that goes from the relay to the horn.

Can anyone trace from their stock horn back to the fuse box and tell me the path and the color of the wire? Thank you!!

 

You're going to need to do a little fishing...but the answer should be here...Good luck

That train horn is sick as hell.

I ended up making my own horn system with a pair of Hella horns wired to a ground-trigger relay that I operate using the horn button on my aftermarket steering wheel. Still a mystery to me where my OEM horn wiring went but c'est la vie
