I have a build thread running for my ongoing overhaul of a 2001 TJ here. This post on installing onboard air felt specific and robust enough to warrant a new thread. I hope I have found the right home for it here in General Discussion.

I knew I wanted to add onboard air to my Jeep and ultimately decided on the Viair 400H compressor with no buffer tank. I did ample homework and think I have found the right solution for my need, which is pretty much just to air up my tires after time spent offroad.
A few points of note:
The many pictures ought to make clear exactly how I installed things, but if anything is unclear, just ask.
The compressor comes with the rubber on the mounting points.
This is the "bumper" I made to help support the compressor. Again, I think this was overkill, but I had the parts kicking around and it was simple enough.
I drilled the hole and added a rubber grommet (above). This lined up perfectly with the barb for a nice, in-line connection (below).
The black air line runs into the cab and ultimately terminates in a cheap plastic filter assembly, as supplied by Ziair. Always clean, always dry. I'm really happy with the setup.
I ziptied the braided stainless supply hose in place above the engine.
I cut this notch and hit it with a rattle can. Nice and clean. You can also see the easy access to the on/off switch.

A few points of note:
- Along with the 400H compressor, I also bought the Viair bracket and modified it for a vertical install.
- I custom made a rubber bumper for the compressor to rest on with some basic hardware and a forstner bit. I think this was overkill given the sturdiness of the bracket, but I'd rather have too much support than too little.
- The 1/4" NPT street elbow and barb fitting on the inlet connects to a Ziair supplied hose that I ran into the cabin for a guaranteed clean and dry source of supply air.
- The only parts I had to buy outside of the compressor, bracket and misc downstream air hoses were the street elbow, and stainless hardware. Everything else is supplied by Ziair with the compressor. **note** I also used two rubber grommets and made that rubber bumper. These are definitely not mandatory.
- The electric hookup is easy. Ground the black wire and connect the red wire to the battery. Ziair supplies a 40amp fuse already wired into the red, hot lead. Simple.
