ARB Compresor Install Notes.
Forgot to post this sooner.
The compressor is actually very easy to install. The wiring loom makes it look daunting, but that's because it has a lot of features.
For the purposes of this install, the contents will only include installation without the included ARB compressor switch, and into a SPOD, or AUXBEAM or 8GANG switch unit, etc.

Basic Instructions
1. Power wiring loom:
Crimp the 2 thick red wires (with the big fuse) together with an end terminal. Heatshrink etc. You can use locking pliers to crimp it together. Just make sure it's tight, and retighten it as you go to make it tighter.
2. Power wiring loom:
Crimp the 1x thick black wire with the 1x skinny black wire together. I did cut about 1/4inch of the thick black wire off, so I could wrap the skinny (18awg?) wire's copper around the thicker wire's copper.
3. Power wiring loom:
Hook the thick power wiring loom to arb compressor via red 12v positive, then ground to battery.
Picture of the Power Wiring Loom & the Mess.
4. Activation Harness:
The other included harness (with lots of skinny wires) is for the switch + activating the compressor & the front / rear locker (if applicable).
4A: Not buying another harness & spicing the wire.
On the unattached plug (pointed out by the green arrow below), there are 4 plugs you can attach directly to the SPOD or relay light system switch you have.
Purple: Power for Switch to activate the Compressor
Yellow: Rear Air Locker Activation
Green: Front Air Locker Activation
Black: Ground for LED for included ARB switch(s)
Splice the spade terminal at the end of the purple & hook it up directly to up a 15A fuse positive on your SPOD/AUXBEAM,ETC, relay system.
Off to the races.
4B: Buying a 3RD PARTY HARNESS so you don't have to splice.
SPOD 4x4 Harness
- Note, you'll need to splice off the spades on this lol.
3RD Party Harness that works just fine.
- Note, it lacks the black wire, but it's not needed as that is for the ground for the LEDs of the switches. If you want to use their included switch, just use the included harness.
- Note2, it uses a RED wire instead of purple, so hook up the red to the purple. Hook up other 3 terminals for cleanliness,
Just plug that into the terminal as noted above by the green arrow & plug the power wire for activation (red or purple, depending on the harness you bought) to the SPOD/AUXBEAM/RELAY SYSTEM.
Green Arrow is the same plug as noted in the screenshot above.
Blue arrow is where the RED wire plugs in from that wiring loom. Again, the red wire is attached to the purple wire in the ARB activation wire loom.
And make sure to swap the fuse.
5. Attach ARB hose connection with teflon tape so it doesn't leak & test.
6. Clean up wires, zip ties, etc.
Install Note for the Fuse:
ARB's included switch is rated for 15A. After a chat with the ARB Tech team, they informed me it's best to use 15A. Usually these activations via relays should take less than 1A, but I followed their recommendation.
Closing Notes
I called up SPOD 4x4, which I thought I bought the harness from, but I actually bought the 3rd party one I linked above (without black wire). They were extremely helpful via phone despite not purchasing their harness. 5/5 for service. I love the fact that I was able to call them and got to someone in 5 minutes.
ARB USA was also very helpful and informative about install. 5/5 for them as well. Took about 6 minutes to get to someone, but they were extremely helpful.
