Switch-Pros Quick Connect Harness Wiring for ARB Twin or Single Compressor?
If you have a Switch-Pros switch panel and are looking to run an ARB Compressor, then there is an easy solution for connecting the two.
The ARB twin compressor comes with a couple of wiring harnesses. It comes with the switch wire along with the power/ground wire. At first glance, the ARB wiring harnesses may be daunting. If you’re only going to connect the air compressor switch and not the front and rear air locker switches, the Switch-Pros quick connect makes it easy.
Wiring the ARB twin compressor direct to a switch is simple and can be done with or without the Switch Pros Quick Connect Harness. If you want to see a photo of the ARB harness cut down to a single switch lead, click this link to see the photo. That photo is of the ARB switch harness with a black and purple lead. The black lead is terminated and the purple is the only live wire running to the switch. The rest of the harness is cut off and set to the side.
Here, we will show you what you need to do to wire the Switch-Pros Quick Connect Harness to an ARB twin compressor.

Switch-Pros Harness three wires:
- Red = Switch
The yellow and green wires are for the air lockers and the red wire is for the switch.
If you are not running front or rear air lockers, you can just end the yellow and green wires and connect a ring terminal to the red wire only, for the switch.
What makes the Switch Pros Quick Connect Harness convenient is that they keep the three wires together which is nice if you ever want to connect the front/rear air lockers (switches) down the road.
Ultimately, the Switch-Pros Quick Connect Harness takes the guesswork out of where to connect the wires without front and rear lockers.
The only question I had was where to connect the ARB wires into the provided ARB clip. Hopefully, this article will answer some of the same questions I had.
ARB switch Harness: Four wires
- Purple = Switch
If you don’t want to buy the Switch-Pros harness, you can simply connect the purple wire on the ARB harness to your switch terminal on your Switch-Pros. That’s it.
The Switch-Pros quick connect harness just makes it simple to connect lockers down the road, if you get there.
Switch-Pros Quick Connect Harness to ARB Harness
Separate the green and yellow wires from the red wire and crimp a waterproof ring terminal on. Depending on the size of your heat shrink, you may want to slide some heat shrink on before you crimp down the ring terminal.
Heat Shrink around all Three Wires
I applied a small piece of heat shrink first to close the gap behind the ring terminal and then positioned another piece of heat shrink around the red, yellow and green wires.
Heat gun on Heat Shrink
Apply a heat gun or lighter flame to the heat shrink and let the material mold around all three wires; yellow, red and green.
ARB Wire Orientation
When your ARB compressor arrives, the plastic clip will not have the wires pre-inserted which may leave some people guessing. You will need to clip the wires in yourself. The orientation of the wires is seen above and listed below.
- Red – Purple
- Black – Blank
- Yellow – Yellow
- Green – Green
Connect ARB Harness to Switch Pro Harness
After you are finished taking the three wires into one, you are ready to connect the ARB harness to the Switch-Pros quick connect harness.
how did you ground the system with the switch pro harness?
It doesn’t need one, that circuit is being grounded on the ARB harness.
I just have the relatively cheap auxbeam switch panel setup and it’s max amps is 60. As far as the ports go, it’s 30amp fuses and down.. so if I hook up an air compressor to it such as the smittybilt 2781, will it be able to handle it? I’m not very good with electrical stuff so I need some insight. Thanks.
Switch Pro questions. I plan on using the trigger wire to be able to turn my rack lights on and off from a separate switch at the back of my rig while at camp. How would I make this connection? And would I use a single pole double throw switch? Thanks in advance.
