I installed a piece of plastic flex loom to keep the wiring harness from chaffing on the air compressor mount.

The vacuum line on the brake booster can easily be re-routed to clear the compressor, just slide the retaining clip from the side of the metal tubing and place it up on top.

Now to get the unit wired and the tubing ran.

Time to get the plumbing installed on the air compressor.

I stopped by a local industrial supply company and had them make me up a Teflon lined stainless steel braided hose, this hose will be the one that connects to the compressor.  With the hose and parts in hand it's time to get started.

These billet caps from Agile offroad are a great way to keep dirt etc out of the couplers when they aren't in use.

20220422_154657-X2.jpg


I'll be mounting the air coupler on the passenger side of the front bumper step.  I found a scrap piece of stainless steel angle that will work perfect for fabricating a mount.  A Porta-Band, Belt Sander and a Drill make quick work of this step.

Test fitting the new bracket for location.

20220422_162345-X2.jpg


The bracket is recessed back into the step making drilling holes very difficult.   I bent a piece of 1/4" all-thread and then heated it with a torch, using the stainless mount as a template it was easy to melt through the plastic...Done.

1/4" Stainless Steel braided Teflon lined air hose. This hose will handle high temps making it a reliable long term solution.

I installed another quick connect at the compressor.  This gives me the option to plug my fill hose directly into the compressor if anything ever happens to the lower connection or the hose...I like options.

Wiring Time!

The wiring that comes with the ARB compressor is quite extensive and includes wiring for diff lockers and a bunch of stuff I won't be needing.   I started by removing the wiring that I don't need so I'll end up with a clean harness.

Here is a the factory wiring diagram, the red X is the wiring I removed and won't be using.  I cut the trigger wiring down and I'll be triggering the compressor through the Switch Pro SP9100.

20220423_163910-X2.jpg


I started with the main power harness.  Here I'm shortening the harness, the ground will be installed on the factory ground stud next to the compressor.

I'll be wiring the compressor to the starter battery.  When running the compressor I'll run the engine so the alternator carries the load.  Located under the hood is the factory jump start terminal for the positive cable of the battery.  The factory jump start wiring is connected to the battery under the van at a terminal on the rear of the battery box.  This terminal makes a perfect point to connect the compressor with a nice short run of wiring.

20220423_101356-X2.jpg


The protective red plastic cap just pops off the terminal.  I'll modify this cap shortly to make it compatible with the new compressor wiring.

20220423_101359-X2.jpg


Adding some marine ring terminals to the ARB power wires.

20220423_102348-X2.jpg

Power wiring ran and snap tied in place.

I used a 90 Deg air tool and a rotofile bit open up a hole to clear the new wiring, this will allow the cap to snap back in place and protect the terminal from accidental shorts.

20220423_104939-X2.jpg

20220423_104954-X2.jpg


Printing some heat shrink labeling for the trigger wire to Switch Pro connection.  This tape cartridge is getting old and is a bit light but it's still legible so I went with it.

Tying the trigger wiring into the Switch Pro, This assembly lives under the passenger seat and controls my lighting and air compressor.

Trigger wiring connection under the hood.

20220424_084920-X2.jpg

20220424_085229-X2.jpg


This is the routing that the trigger wire takes to get from the passenger side seat base Switch Pro unit to under the hood.  The wiring crosses over from the passenger side to the drivers side under the flooring (There is a built in wire chase for this purpose), then exits the drivers base and runs under the plastic on the drivers foot well and out of a rubber grommet where the roof AC lines used to run.

The controls to the Switch pro are in my headliner, located within easy reach just above the dome light.

With the compressor wired and now fully installed I turned my attention to setting up a dual tire inflation setup.   This setup will allow me to fill (Or deflate) two tires at once.  Since I run my front tires at a different pressure than the rear I'm going to make a two tire setup so I can fill the fronts as a pair and then the rears as a pair.  You could also make a 4 tire setup with the addition of two more splitters.  I'm making up two of these units, one for myself and one for my father to carry in his Tacoma.

You can buy these dual & quad inflation setups pre-made but the cost is higher and with the Flexzilla Pro hose I can change the length of hose as needed, if I get a hole in a hose I can shorten the hose in the field with the re-usable ends and keep on using the setup.

This setup costs $135 to make, including all three sections of air hose and the digital gauge.

After measuring enough hose to reach just past the rear of the van I cut the hose at that location.  I wanted the main hose to be long enough to use by itself at all 4 tires if I choose...I like options!

20220424_093838-X2.jpg

The ends are aircraft aluminum, you slide the hose through the flexible whip then press the hose onto the barb.  When you screw the fittings together it compresses the hose and locks it in place.  Simple, fast and works great!

Both units finished.

20220424_145748-X2.jpg


JT Tire Pro Deflators.  I carry a set of these in the van to make quick work of deflating the tires.  You set the desired pressure and screw them onto each tire.  All 4 tires will air down till they meet the set pressure and then they will seat and stop blowing, unscrew the units and your ready for off road travel!  I like these units as they save a lot of time if your deflating all 4 tires over doing each tire individually.  I've found the accuracy to be within a couple pounds of set pressure, perfect for deflated tires.

After using the deflators to drop the pressure in the front tires to 25psi It's time to test out the new compressor and manifold to see how long it takes the compressor to air up the two 34" tires from 25 psi to 50 psi.

Attaching the air hose to the valve stems.

20220424_142121-X2.jpg

20220424_142128-X2.jpg


All hooked up and ready to go!

20220424_142528-X2.jpg

20220424_143747-X2.jpg


The new compressor setup works GREAT!  It took exactly 3 minutes to fill the two 34" tires from 25 psi to 50 psi.  This will make short work of airing tires back up for the highway after off road travel!

20220424_143730-X2.jpg


Short video showing the setup in action.


 

And all packed up in the storage bag, ready for travel and use.

Great mod for your van. I’m about to mount my Viair under the hood in the second battery location and run lines fore and aft. But the speed and CFM of the ARB twin is impressive!

I've got to get a labeler. Pricey little machine but would make my life so much easier when I need to diagnose a problem.
