I finally got around to installing my Air Horn set up. I bought this off a guy who had it for his jeep so there were a few things I needed to change so that I could mount it up on my GMC Sierra 1500 AT4. The parts:
1- Kleinn 6450RC Air Compressor
2- Kleinn 6353RT 2.8 Gallon Steel 9 port Air Tank
3- Set of Hornblasters Shocker XL Train Horns
4- Hornblasters 1/2" Black Widow Electric Air Valve
5- Kleinn 2151 Pressure Switch, 110PSI ON / 145PSI OFF
6- Kleinn 52155 Mechanical Safety Relief Valve | 1/4" Male NPT | 155 PSI Pop-Off
7- Kleinn Compressor Air Intake Relocation Kit "Snorkel System"
8- Model 340: 12-Volt Sealed 30/40-Amp SPDT Standard Automotive Relay
9- Hornblasters Stealth Spare Tire Delate Bracket
These are the main items, lots of other little things used for the install. Let me know if you have installed one before and if you used an Auxbeam. I am hooking mine up to an auxbeam and having some issues with acquiring a good ACC fuse tap.
This what I bought and started out with
Had to add a mounting bracket for the Air Tank
I ended up switching the mounting bracket to the Hornblasters Stealth Spare Tire bracket and moved the horns over and started mounting the Air Tank and Air Compressor.
