Last week I was also able to finish up the on board air system with an ARB Air Compressor Pressure Control system. If you are unfamiliar with ARB Pressure Control system, it allows you to configure preset tire air pressures in an app and then inflate or deflate your tires by simply connecting a "whip" to each tire and then hitting a couple of buttons in the app. On my setup I can inflate all four of my stock tires from my Overlanding pressure of 20psi to my Daily Driving pressure of 36psi (I'm still fine tuning my daily pressure) in just a tad over 7 minutes. Deflating from 36psi to 20psi take about the same amount of time... if you trick the system a little. This system, at least on my truck, has a hard time deflating to the last psi. It will release some air which will drop it down to the target psi and stop. The pressure rises 1psi once the valve closes and this sets off a cycle of very small adjustments trying to deflate that last psi down to the target. What I have found best to do is set your target psi to 1psi less than what you really want. This way the system takes it down to your true target psi and you can turn the system off before it goes through that whole cycle mentioned above.
The mounting bracket they include did not work for my needs, so my hotrod building neighbor made me up a bracket to mount it to my passenger side half bin MOLLE panel.
I then rounded up everything else I need to powder coat and hit them all with a satin black that is a very close match to the SmartCap.
Here is everything put together and attached to the pressure control module.
Previously I had hard mounted the Schrader valves to the truck, so at this point I just had to run the tubing from the four corners back to the compressor area. That was done with parts from the Up Down Air system that I had bought for the Gladiator and never got around to installing on it.
Of course, the BedRug had to be pulled back again to run the tubing up and into the bed of the truck.
The pressure control unit had to be tapped into the ARB compressor harness so that it turns on when the compressor does. For this I removed the pin from the connector and spliced the new wire into that and put it back into the connector.
