That depends worldsmysterie,

If it's a stock one you just push in on the horn button and turn and it will come off.

It could be the horn relay... or the brush contact in the button or a wire between the button and the relay or from the relay to the horn...
lots of possibilities.

Did you find the problem? I ALWAYS test the wiring at the horn on the radiator support FIRST.

Take your voltmeter and set your voltmeter to a scale over 10 Volts DC (VDC). Take your volt meter and put the black (negative) test lead on the negative terminal of the battery or in a good solid connection on the body of the truck, then unplug the wire from the horn and put the red (positive) meter test lead in the connector that plugs into the horn. Set the meter down so you can see it from the driver's door or from between the crack in the bottom of the hood and the cowl area out over the motor. Press the horn button and see if you see the meter jump from 000 to 12.xx volts DC. Also, listen for a "click-click" sound coming from the horn relay next to the battery and the starter solenoid. If the meter doesn't change then carefully unplug the horn relay and clean the terminals on the relay and take a small small small screwdriver and try to scrape any rusty residue from the wiring harness connector that plugged into the relay (this is what fixed the horn in my '68). Plug the relay back in and watch the meter and listen for the click again. If you get nothing then go back into the cab and start your troubleshooting in there.
