I'm a little closer to having my On-Board-Air done. I've mounted the 1 gallon tank under the tub. I also fabricated a bracket to hold the pressure switch, T's, and fittings under the hood. To keep the under hood quick connect port clean, I used a fitting with a pressure gauge, this also allows me to know what the pressure is in the system. I also installed the ARB quick connect fitting on the rear of the Jeep behind the license plate. This should keep is a little cleaner, and not in a potential high damage area. Now to get the hoses from the compressor fabricated, and install the arming switch. The only bad decision I think I've made, is the arming of the system, will be by a switch that grounds the pressure switch circuit. If I'm not careful, I could leave the compressor on when the engine is off, running down the battery.
