CJ7 Horn wiring - JeepForum Jul 23, 2012Does anyone know what color the wires in the original wiring harness went to the horn on a 79 CJ7? I have a red and a yellow wire hanging loose in the general vicinity of where the horn is mounted. Not sure if these go to the horn or not. Any ideas?

NO it's not the old wimpy beep beep import sound. It's your basic FIAM Snail shell Horn but has a anti splash shield over the opening. It's loud, deep sounding and cost just over $12 bucks.
