Alright, so I came across a set of axles with ARBs, a 30 front and 44 rear. The front is a simple LP 30 with 27 spline shafts. Rear has Alloy shafts. The whole deal came with the arb compressor, but no switches. I've got a 3 prong safety switch, the one with a red safety cover. Unfortunately, I'm a funny when it comes to wiring things. I have the harness for the compressor, but the ends were cut from the guys that took the parts off the TJ. I quickly searched on here for someone that did this, I didn't go into depth with build threads and such. I have the wiring diagram, but it seems different from the wiring harness I have. I'm pretty sure it's an older set of locker and compressor.

Does anyone have input on this? All I am trying to do is wire the compressor because it has the air chuck attachment for tire inflation. I'll get the lockers/ axles in at a later date.

Isn't there only 2 wires coming from the compressor? Positive and negative.

Yes, but that's for the battery. There are 4 wires bundled together that are for the switch. I saw that in the diagram. The ARB switch requires 4 wires and 5 connections, a red for power, yellow and green for something, and a black that I'm supposed to splice and make 2 grounds.

I emailed ARB and they let me know what compressor I have. Hopefully they can tell me whether or not I can use my switch that I have laying around.



That's the bundle for the switch.
And the other is the power from battery

Gotta have a relay too.

Got one. And a 30amp fuse

Emailed Arbusa. They told me it was fine to use a trail at switch for both lockers and the compressor, all separate of course.
