How do you keep mud out of the front-facing air connector?

If it is a ARB quick connect, put the ARB cover on it.

How do you keep mud out of the front-facing air connector?

Good question, but I believe it may have been just answered!

I was planning to use an old quick connect with the end sealed, but a chair cap is a much better idea.

Once it became clear the ARB compressor would fit where the headlamp squirt reservoir was, I worked on mounting one there. I had the inner wheel well or arch removed because I was searching for rust. this allowed me to fit a compressor mount more easily. Along with the attached nuts used for the squirt reservoir, i added a 4th. Again this was possible because the arch panel was removed.

I wanted the be able to pull the compressor out easily in the future so I made 2 rubber mounts for the almost inaccessible lower 2 bolts.

Here's a view from above with the mount in place.

Here is what the mount plate looks like. Steel is 1/8' stuff I had lying around.

Those studs are flat head screws welded on the back side

Here is is with the ARB mount bolted to it.

Here is the compressor mounted.

I used Anderson power pole connectors. They are rated to 40 amps...maybe 45.

Here is the whole mess in place

I decided to put the power switch in between the 2 batteries.
I welded a threaded M8 stud to a bent piece of steel for the switch bracket.
This was mounted through a factory hole in the battery tray support.
I made a little plastic cover for the quick disconnects.
I installed a one foot air hose and put some foam rubber over it to prevent the chafe.
I put a tee on the end of the air hose that will lead to tires.
I plumbed a 60 psi pressure relief valve on the tee so I will hear when the tire is full.
