I have air horns on my 92, but I ran them to a seperate switch, since the stock horn didn't work when I got the truck.
It seems feasable to me if you ran your compressor wire to the stock horn, put a spade terminal on it then unplug the wire from the horn, and plug the new wire into the stock wire. In theory it should blow the air horns, just like it did the stock horn when you pressed the button.
That's what I am trying to figure out how to do. I already have a relay hooked up to the air horn. I just can't figure out what to hook it to or where anything is.
You just need constant power from the battery, ground, and the stock horn wire should activate the relay.
And ground the new horns. Disconnect the stock horns.
