Anyone else run into problems with the EVO MFG mount for the ARB onboard air in a 2012? First off, the heat sink/mounting bracket on the compressor is backwards from EVO's instructions. Not a big deal just undo the bracket that holds the air tank on and the two hex bolts on the heat sink and flip the bracket. Next problem is EVO wants you to run the bolts from the bottom up but the bolts supplied by ARB are too long. If you run them top down as ARB intended they will hit the master cylinder. Had to get new shorter bolts and add a washer. Now it is a pita to tighten the nylocks so I pulled the mount off the comp, mounted it to the bracket then back on the comp.

 

So I finished the install, couple differences from the Project-JK version. I got the package deal from Northridge4x4.com that comes with an ARB compressor, EVO MFG bracket for 2012, hose and inflator with guage. I had to buy four 6mmx16 hex head bolts but they were still too long. The bracket is 90 degrees from the Project-JK write up, and sits directly over the brake master cylinder and tolerence is very tight. You have to mount the bolts upside down and they shouldn't touch the compressor on the other end or you will transfer vibration to the bracket. I ground a couple more millimeters off so they are flush with the nylocks.





Once mounted and wired into the battery etc as in the Project-JK write up but I followed the rear wiper wash hose through the firewall on the driver side instead of passenger.






I cut a template for the switch out of cardboard then in the kick panel under the steering wheel. It is tight behind there so i needed to bend the conection tabs to fit the switch in. Its a sqeeze to fit between the ridges in the back of the kick as well but carefull trimming with a blade and you can get it straight.






Hard to see in the dark but it looks factory and there room for more switches if you add lockers or lights.
