Might want to check out Hadley products.

They list all kinds of compressors and air horns. I picked up the Hadley Bully-Electric Dual Air Horn Kit (code: XXXH00961EA). It's real loud! Dealer installed compressor and horns between grill and radiator. Hooked the horn wires right into steering wheel horn pad. Threw the wimpy factory horn away. Horns are metal so they won't crack in freezing temps. Plus, it comes with an air hose that attaches real easily to compressor through the grill slots. The one I chose is a bit pricey, but I figured with air horn and air hose - it's kinda like a "two-fer".

I noticed about midway on frame(outer side) there is a metal plate coming down verticaly with holes for mounting a bracket for the male coupler.It could be mounted straight down and cover it with a rubber cover when not in use so dirt doesnt get in.Easy access to hook up air hose .Its out of the way enough so it doesnt get hung up off roading.Also it wont get in the way if you remove sidesteps for serious offroading.

jp's-h3 whats happening with install? Are you spending to much time in the helicoptor?
