ARB single compressor wiring help

[The Ontario jeeper]

I’ve got a ARB rear locker in my rubi. Factory front
I have a ARB single compressor with 1 locker solenoid on it. The ARB wiring harness I’ve got has a spot for 3 switches. I understand how the system works but I would like to have it so my rear locker gets air as soon as I power up the compressor. In order to do this do I just splice the locker solenoid wires into the same positive and negative wires my isolation switch would plug into? In my head that would effectively turn both the compressor and the locker solenoid on as soon as I flick the isolation switch. My front locker is being supplied with air via the factory pump and its own switch. This compressor will only be sending air to the rear locker and nothing else.

You can do it that way, I'd encourage you not to in order to avoid crash locking the locker. You ideally like or want the compressor up to full pressure before you shift the locker. The creates a more positive shift and helps avoid a partial shift that can shear the tops off of the locker clutch teeth.

Okay I’ll order another switch and wire it up properly then. Thank you.

One more quick question. If I understand the instructions correctly I don’t need to have a switch plugged into the wires for switch 2 since I don’t have a solenoid for it correct? Only switch 1 and the isolation switch?

Correct. As long as you use a switch and the Switch 1 matching part of the harness, it will work. If you use the front part of the harness or Switch 2, it won't get power until the rear switch or Switch 1 is closed. (may be ground, been awhile since I looked at the diagram) Either way, the harness is constructed so the rear locker switch or Switch 1 has to be on before the front switch or Switch 2 will work. The isolation switch turns on the compressor and then allows switch 1 to function.

Awesome, thank you!

I have the same compressor, also using it for my rear ARB locker, still have OEM front locker. Using 2 switches, one for air compressor, the other for rear locker. I also have the air up kit, which gives you the air connection and a removable hose assembly. I have the compressor mounted on the tray below the brake booster.

I also have 2 switches, 1 for the compressor and 1 to the locker. I like to let the compressor to run before the locker to make sure it has good engagement. Like Ashim I have it mounted in the same place.

Yeah that’s where mine will be mounted too. It’s where my factory front pumps were relocated to as well
