Electrical Dunce - Help needed with SPOD and Arb Compressor

Yesterday I installed my SPOD and Arb 12 Volt Air Compressor (CKMA12). Physically they are installed but the electrical connections baffle me (or I'm over thinking it).

My purpose for this setup is ONLY for the onboard air. I will not be installing air lockers on this jeep.

In addition to the massive Arb wiring harness, I also have the Arb harness from SPOD. I do not believe that I need to wire the Arb to the battery as this unit only pulls 26 Amps and the spod should support up to 30 amp.

How do I wire this up to make it work?

Any help would be greatly appreciated.

the sPod has the rely built in so all you need to do is wire the + & -( from the compressor) to the sPod with the proper fuse.

But how about the pressure switch? I can understand running the power straight from the compressor too the SPOD but do I need to do anything with the pressure switch?

OK, I looked into it a little more. You need to run the + of the compressor to the + of the sPod. then run the - of the compressor into one side of the pressure switch then the other side of the pressure switch to the - of the sPod.

Awesome. Thank you for your help. I greatly appreciate it. I'll confirm how this works out in the next day or so when I get a chance to do it.

You can't run the circuit through the pressure switch as that switch is rated at only 20 amps. CKMA12 is also fused at 40 amps with a start up current draw (for a few milliseconds) that can approach 100 amps when restarting under load. The easiest way to do the job is to control the ARB harness with the Spod output. You only need the ARB underhood harness and not the dash harness. Hook up the big black and red leads to the battery from the ARB harness. Plug in the included relay into the yellow plug and connect the red and blue wires to the pressure switch on the compressor (doesn't matter which way). Next plug in the compressor motor to the plug with the big red and black leads in it. Lastly find the 4 loose wire on the ARB harness (black, red , green, yellow) and connect the red one to the output circuit off your S-pod. That will turn the compressor on and operate it as designed via the pressure switch and relay in the ARB harness. Running directly off the Spod is pushing it for current capacity and performance of the compressor is likely to suffer as a result along with possibly damaging your Spod.

Tie back black, green and yellow (as unused)?

As much as I was trying to avoid using the huge ARB harness, more to just keep everything very clean looking, your comments make a tremendous amount of sense. The last thing that I want to do is burn up the SPOD and/or the compressor. Thank you for the detailed write-up along with others in this thread. I can finally make sense of all of the connectors.
Happy Wheeling!

If you get lost with any of the wiring on the ARB side just ring them and ask for the Tech Dept. The guys there will walk you through the process as needed.

Arb with SPOD install

I'm DONE. I used not only the "long" ARB provided harness but also the SPOD "Arb harness" that I purchased extra and everything came out great. I will say that I shortened the ARB harness where I could (mostly around the battery connection I took off a good 16 inches of unneeded harness). I still ended up with a coil of wire near the SPOD itself. Perhaps one day I'll cut that up and make new connectors for it.

Thank you everyone for your help. Now on to the next project. Happy Jeeping!!!
