ARB Twin Compressor
ARB Twin Compressor
Welp, finally got around to re-installing and finishing up the wiring on the ARB Twin Compressor from my previous 4th Gen. Had a Bandi mount on the previous rig, so I knew I wanted to get one for this rig. I opted for the one with the 1 gallon tank, and installed it. All in all, I am super happy with how it all came out. It fits like a glove in the corner section of the engine bay.
Installing it was a bit of a pain, but mainly because the clearances are so tight in that corner of the engine bay. If you do this mod, I HIGHLY recommend you take out the airbox. It is just a few bolts and it gives you so much more room to be able to install this. I tried installing a few ways, but found the easiest way was to put the mount together, install the air tank on to it, mount it in to the truck, and then mount the compressor to it. Easy is a relative term here, but I have been able to take it apart and put it back together in about 20 minutes now, so I think it is pretty easy.
Ended up running leader hoses from the ARB to the tank, and then the tank to a manifold. The tank has 4 fittings, so one is for air in, one for air out, one for a dump valve, and one is plugged. I then installed the manifold and have a safety blowoff valve on there as well as a quick disconnect for an air hose. I opted for the manifold because I may run an airline to the rear eventually and wanted the option for expandability.
Wired everything up to an AOB switch and man, what a pain in the ass. I wired it numerous ways and finally got it how I wanted it. I wanted the AOB switch to dim with the dash lights and I finally figured it all out. To wire it up to the "Isolating Switch" part of the ARB harness, you need to do the following:
AOB Blue - Connect to ARB Blue/White
AOB Black - Connect directly to factory gray wire on wiper heater switch
AOB Red - Connect to ARB Red/Yellow
AOB Green - Connect to ARB Red
ARB Black(x2) - Tie both wires together and ground to chassis.
ARB Blue/White - Connect quick disconnect end to AOB Blue. Connect diode end to factory green wire on wiper heater switch.
ARB Red/Yellow - Connect quick disconnect end to AOB Red. Connect diode end to fuse of your picking on interior fuse box.
ARB Red - Connect directly to AOB Green
The wiring was confusing, so if anybody has any questions, let me know. Pictures of the finish product below!
