Went to the local Pick N Pull and found a set of 4 Cadillac horns from a 1982 Caddy for around $25. Going on my 98 F150. Love the sound of those! Almost as good as a semi horn. Just need to figure the wiring and relay issues out. Figure 4 horns will draw more amps than 2. Any input is appreciated. I will post results when done.

 

Wow, no follow up and no replies - i know people have done these, but the choice of relay and mounting always seem to be trade secrets.

Yup, i didn't post that picture for S&G's, would be useful information to have.

 

Appears to not be common mod.
