I'm wanting to put something together to I've heard of people going to the junkyard and getting an air compressor off a car with air suspension

Okay Justin,
Here is what you will need. (you may be able to find better prices, the links are just to provide a good part number to search with)

Air Horns: See OP (that particular one has a build in solenoid)

Air Compressor:Viair 10010 100C Air Compressor

Air Tank: (this tank is 5-gallon tank, a little large for just horns, but when I do my setup, I am going to have a large tank with hose fittings for filling tires or whatever) 1-gallon is plenty for horns 5-gal Air Tank

Pressure Gauge For Tank: (this one is tank mounted as it is cheaper, but you could mount one in-cab)Air Pressure Gauge

Switch for the Horn: or you could use a relay setup to trigger them off the factory horn button

Switch for The compressor: or you can hook the comp up on an ignition hot wire, but EVERY time the tank loses pressure, the comp will run

Pressure Switch for Comp: (when comp is on, it will fill until the pre-determined pressure, then shut off)Pressure Switch for the Comp


Hope that helps. If you have any questions regarding wiring or setup, gimme a yell. Also, you will need air lines and fittings, you can find those!

If you add up the shipping and everything one the compressor, tank and switch, and then shipping from everywhere else, it come to about 185 plus. I found this already put together for $189 and right now its 170 with 10% off.

btw...whats the built in solenoid do on the horn?

[05_PSD_Erik]

when you apply power to the solenoid, it opens and lets air through, blowing the horn!

Also, that is a good price on that pre-wsetup kit. Just add a couple lines and switches and you are in buisness. Let me know how it goes if you get the horns as that is a GREAT price
