On-board ARB Dual Compressor
One of my favorite mods so far is my on-board air setup. My Jeep doesn't have ABS, so that left the tray empty and available. I had seen other people who had fit the ARB Dual Compressor there, and that was the route I decided to take.
For this setup I used the following parts:
To fit the compressor in there I found it was easiest if I unbolted my clutch master cylinder, as well as unbolting the vapor canister. I also had to finagle it under the main firewall wiring harness, which actually ends up resting on the compressor itself. I ended up adding some extra wire loom around the harness just to be safe.
It is definitely a tight fit, but I was able to get clearance on all sides of the compressor. I marked out where I needed to drill on the ABS tray, removed everything, and reassembled. The compressor has to be bolted down from underneath the Jeep, that was a fun process .
Wiring is pretty easy, just up and around the firewall. I did have to extend the included wiring a bit.
You can mount the quick connect onto the compressor itself, but I wanted easier access, as well as wanted to limit how hot the quick connect would get.
I decided the best place for the quick connect was right behind the vapor canister. I used a piece of 16ga steel, cut and bent it until I was happy with the shape. The bracket for the canister already had two small holes on it, I enlarged those and used them as a mounting point for my bracket. I then assembled the fittings and the hose, making sure to use plenty of high temp thread sealant.
Lastly I needed a switch for controlling the compressor.
The compressor comes with a harness for use with controlling ARB lockers. For my setup I just needed an on switch, so I instead opted to make my own harness. I had a set of TJ Rocker Switches from eBay and used the "ON" switch. While the switch action feels like crap, they do look factory, so we'll see how it holds up.
I also made a small splash shield for below the ABS tray bracket to limit some muck. While it probably does help, the compressor still gets a bit dirty.
Eventually, I would like to relocate the air filters for the compressor up higher; they are splash proof but just to be on the safe side. It might be challenging due to the limited space between the compressor and the fender, but we'll cross that bridge when we get there!

For this setup I used the following parts:
- ARB CKMTA12 Dual Air Compressor.
- ARB 171302 Inflation Accessory Kit. Primarily for the quick connect, it's awesome and spring loaded!
- 1/4" NPT Bulkhead Fitting. This is for mounting the quick connect to the bracket. You only need one, could only find a link for two.
- Viair 92804 18" Leader Hose.
- 16ga steel for a bracket.
