Long overdue update to my locker setup. The locker itself is great...still worth every penny. No problems whatsoever. Having since installed a few other ARB units in a few trucks over the years, I still prefer the TJM. Unfortunately, I have a feeling these won't be available much longer.
I've made several changes to the onboard air setup that supports this over the years. I eventually moved the MV50 out from the cubby area because it was too loud. It was reinstalled under the hood:
The 1/2 gallon air tank also got removed from the system. It was nice to have some reserve for air locker usage, but wasn't too useful for other functions because it just meant additional compressor run time to pressurize it. I may incorporate it on another project.
At that time (I think), I had also wired in a digital pressure gauge in the glovebox plus installed air/Schrader valves at each tire for use with 3' whips for a tire inflation setup.
The petcock gave me the ability to also dump air, which is nice to get everything to a consistent PSI. I also re-wired the digital pressure switch to have switches to manually override the power and relays for other functions. Made the whips with clip-ons, hose clamps, and a cut-up Harbor Freight air hose.
Then in 2020, the installation of ARBs in Rockit's QX4 prompted the need for an air compressor in his truck, so I pulled my setup out, acquired cruise control parts to match his setup, and made some brackets to shoe horn an ARB into his truck:
This took a lot more effort than I had anticipated because of the cruise control pieces. For reference, the space normally looks like this:
I made 3 brackets total: one to move the pump closer to the fuse box, another to move the 'bulb' closer to the firewall, and then the compressor bracket that mounted to the strut mount:
The original plan was for me to acquire a CMKA12 just for mocking up Rockit's setup, but the distributor for the shop I bought from sent me an open box unit, so I had to deal with some BS there. The shop cut me a discount and I just kept the unit and made myself a bracket for my truck:
While at it, I added a small fuse box and some relays for future items. I also needed to rewire the digital pressure gauge a bit to handle another solenoid for deflation air dump, but also rearranged the plumbing to make it a little more compact for storing in the glovebox.
Everything is still controlled through the all-mode switch:
Didn't mention it earlier, but these panel bezels are interchangeable on the radio bezels. My truck originally had a panel with a pocket and 2 switch blanks, so I bought one for an LE. It just snaps into the bezel. The all-mode switch functions as such:
2WD: Inflation/deflation mode. I attach all the whips to the tires, and can either auto-inflate to my preset PSI on the digital pressure switch, or I can turn off the compressor and open the dump solenoid and/or petcock to deflate.
AUTO: Compressor on; charges the system to 100 PSI for locker usage while driving, or for quick-connect usage (rear bumper and under hood) while stationary.
4H: Rear locker engaged.
4LO: Front and rear locker engaged.
If I haven't mentioned it here previously, I hate dealing with pneumatics. These projects take so much effort to do. I have a slow leak somewhere and have no interest in finding it, let alone ever touching this system again.
