ARB Twin OBA Factory Aux Switches

[watican]

Hey guys, looking for some advice here. Someone decided to try to PIT maneuver me on the interstate going 75mph in my Ford adventure-mobile, which made it roll over, so now I get/have to build a new truck. I ripped a bunch of the goodies off of the old rig in the junkyard, and am figuring out how to proceed. I have a '22 3500 with the factory Aux switches, and step 1 in the build is OBA. The factory relays don't seem to support enough current to run the ARB twin on one relay, and I'm not going to use two.
I'd like to use the factory switch and the ARB harness, since I'm planning to put air lockers in it when they come around. Does anyone know how to use just the signal output from the factory aux switch with the ARB harness to kick on the compressor, with said compressor still being wired straight to the battery?

Appreciate the help.

I don’t have first hand experience with this exactly… but the general idea is you would wire the arb to your own high power relay wired directly to battery, then use the factory aux switch to “activate” the high power relay.

Oh, I forgot to include the wiring diagram that ARB provides, sorry about that. Added to original post.

I believe that the compressor already has it's own high current relay that's used with the supplied switch(es).

Plenty of PW folks have them, look through the threads and contact someone that has one installed

ARB Compressor - Need Advice for Wiring

Using the under-seat (passenger) mount. Hoping to find someone else who has gone this route. Attempted to use the search function but it either doesn't work or I just don't know how to use it. Per ARB's instructions, there is a RED/YEL wire that must be tapped into a ignition/ACC power...

ARB Compressor mount - under hood or in floor bin?

I purchased the NH Overland bracket to install an ARB twin in the engine bay. I liked making it accessible and out of the way. The only thing I don't like is that it's right above the headers/engine and exposed to moisture. I just happened to be on SDHQ website and ran across this storage...

ARB Dual Compressor install

Hello everyone. I wanted to post this to share an install I made on my 2018 PW. I'm sure everyone is aware that finding a good place for an air compressor is anything short of challenging. I searched for a while and really never found a place I was happy with. So, I decided to throw in the towel...

One aux switch for compressor and wireless controller

New guy here. I'm planning on ordering an ARB twin and Pacbrake wireless air spring control (https://pacbrake.com/product/hp10325-amp-wireless-air-spring-controls/) for my Timber Grove CRM bags. I will also use the compressor as OBA. My thoughts are the power of the ARB would eliminate the need...

Onboard Air - ARB Twin

I finally installed my ARB Twin compressor that I had on my last 2500 in this one. I left my wiring harness in the other truck when I traded it so I made up new cable sets which took a while but are perfectly cut to the right length. In my last 2500 I had the compressor mounted behind the rear...

NHOverland sell what they call a “trigger wire” which pugs into the ARB Twin switch

NHOverland sells what they call a “trigger wire” which plugs into the ARB switch loom connector. This single wire connects to the factory aux swithes. Hang o to the switch wire bundle that comes with the compressor in case you want to install the ARB manifold & air lockers.
