The horn does not work. The fuses on k40 tested good. Where is the output wire for the horns? What else should I test? Ground is good.

Take and apply 12v to the horn directly while it's unplugged from the harness, verifying the unit actually works. Also, take a peak at your clock spring, mine had let go over time and that's where my issue was.
