My stock horns were not working, so I ordered a Gampro 12V air horn kit from amazon. It's one of the ones with its own little compressor. Came with an inline fuse already installed and its own pre-wired relay. Seems like a pretty straight forward install. Just a couple of questions for anyone that has already done this install, or is just more electrically savvy than I am.
I believe the stock horns on my 1990 F250 were the problem, as I can hear the horn relay clicking when I press the button on the steering wheel, but no "honk". So when I go to install the air horn kit, do I use the wires that were going to the stock horns? Or do I need to pull all that and power the new horn from the pre-existing relay that's behind the glove compartment? Does it matter if I have two relays?
