I was prepping the coach for Quartzsite and fixing all of the little things I do once a year. I had a project that I been waiting to do and got it done yesterday.
I know some coaches come with both a regular horn and air horns. There have been occasions where I really didn't want to blast someone with the air horns, especially when driving through town. I've also missed them when the coach is aired down and I just wanted to give someone a short toot, like the guy getting to close as he backs up.
I grabbed a set of horns off of a crashed Ford. I didn't want one of those obnoxious chrome horn buttons with the black knob, so I bought an old style starter button. You can see the chrome button to the left of the column. The location is easily accesible.
I attached the horns to the frame, just inside the generator door on the driver's side. The mount was already attached tot he horns and worked/fit perfectly.
The wiring was simple because of the placement of the switch and the horns. I just ran the switch wires down through the steering column boot and to the horns. I picked up the power from the adjacent driver's side power center. I added a fuse and plugged it all in. The Ford horns are pretty loud and have a good sound.
I got the horns for free, so the whole project cost about $20.00.
