I have the wolo challenger EV air horns in my truck. I just put a wire into that spot under the stock relay. It does run to another relay. I put the airhorns onto the radiator bracket behind the grill. They are mounted horizontally. The airtank is where my winch will go when I get one. The compressor is next to the airbox. Compressor is hooked up to an accessory + (that way it only runs with the key in the on position.)
They are about 125db and sound like an 18 wheeler is behind you. :bounce:
You can just see the chrome caps.

the wire going into stock relay: Stock horn is still operational
