Horn not working. Need help

I need to get plates on my van tomorrow so we can head to Colorado, but I need the horn to work to pass inspection. When i press the switch on the steering wheel, you can hear the really click under the hood. There is power to the relay. I ran a jumper from the battery straight to the horn and they honked.

Cannot seem to trace the wires running from the horn back to where they go.

Does anybody know what color the wire is coming out of the under hood power distribution box going to the horns from the relay?

If I knew that I could just run a new jumper to replace existing wiring.

Try a new relay?? Can you swap one of the other relays in to test??
Will the horn work if you provide jumped power where the relay is located??

Relay was clicking, but I switched with another anyways. It didn't do anything.

Like I said in the first post, I ran a wire from the battery straight to the horn and that honked it.

I Looked up some diagrams online, and figured it's the yellow with the green stripe coming out of power distribution box under the hood. I tapped that wire and ran a wire to the horn's, and I'm all good now. Honk honk.

Horn doesn't work? Use finger!

No seriously, for a quick horn can you wire up a floor switch? I've seen floor switches for horns and bright lights in some older trucks. Might be a simple way to get one for the monent so you can get on the road.

Old school high beam switch? I still use one in my Bronco, but I'm not sure you can even find them anymore.

Yeah my bronco and my 53 Buick both have floor switches.

My issue was resolved by running a new wire from the power distribution bbox on to the horns.

I kind of like these things, either for horn or brights.

I have this Moroso switch panel mounted to my roll cage in my Bronco. Switches control the air compressor, rear locker, LED light bar, and rock lights. I used the push button 'start switch' to control my horn.
