So my dad found the 3 Cadillac horns he came across in a junkyard Lord knows when. And he found this old VW Beetle horn he had and gave all four to me.
The VW horn works because we tested it.
I don't plan on using the VW horn on my truck......I plan to hook up the 3 Caddy horns to be the truck's main horn and then get an Ooga horn to use as a gag.
My dad installed an extra horn button under the dash for when the horn button on the steering wheel went out. When I fix that, the Caddy horns will hook to that and the Ooga will hook to the extra button.
