My horn stopped working where is the horn mounted?

Number one is the front cross support, number 2 is the horn. Don't know if you can visually see the horn from top or bottom? Removal info says to raise and safely support passenger side front tire, remove tire, remove or partially remove the fender lining, ever how much it takes to get at the horn.

Here is a test light guide to see if it is getting power with the horn wiring diagrams below. . https://www.2carpros.com/articles/how-to-use-a-test-light-circuit-tester Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.
