So the previous owner has an air horn and air tank hooked up to the truck. There is only one wire going to the air horn, and the horn still functions from the steering wheel. If I disconnect the wire from the air horn and touch the battery with it my factory horn works, what do I need to hook that wire up so my factory horn will work.Thanks in advance.

i had air horns and just disconnected the wire and plugged it back into the factory horn.

I tried that,I hooked up the wire that went to the air horn to the factory left horn that had been disconnected and it didn't work

there should be a wire going from the one mentioned to the second horn.

There is a wire going to the second horn, it was already connected

I appreciate all the responses and help, so my factory horn has 2 horns, I'm guessing a high and a low, one was never unconnected and one was disconnected and that was hooked up to the air horn, when I got the horn on my steering wheel only the air horn would work.......

okay, hmmm are the factory horns grounded? I wonder if you factory horns stopped working and thats why the Po put air horns in
