horn

The 2001 Ford Ranger Edge Supercab I recently bought has had some "modifications" (and that is being kind :sad:) done to parts of the electrical system. I am fairly adept with electrical work so not too much of an issue, but I am running into one with the horn. Previous owner replaced the horn...

97 ranger splash has been wrecked we have replaced steering column, resetc the srs light (clear code) new horns swapped relays and fuses still nothing plz help

So i have an issue i dont know if im reading it right but in some of the diagrams ive seen the horn and cruise control wiring run through the radio fuse... and nether of them work and i well you need a horn to pass inspection, the only problem is the fuse for radio is doesn't work as i have...
