The wire coming from your steering column should be a ground. With a meter make sure it is grounding when the button is depressed.
The horn relay has 3 terminals. Make sure you have 12V going to the power terminal of the relay. Ground the ground terminal to the cab with a screwdriver and you should have 12V to the horn terminal.
Next apply 12V to the horn. It should honk.
If all these are OK then wire it up and it should work. If any of the steps don't work, that is where your problem is. | | |
