ARB dual compressor mount: Slee or SDHQ?

The twin has an electric cooling fan, and I’d personally want to remove the cover and make sure the crank and such isn’t exposed like with many oil less compressors
ARB claims IP55. Their marketing jank claims sealed. I can't personally vouch one way or the other, I stuck mine under the hood in the typical US driver spot.

The cooling fan is 100% not sealed - I could stick a pencil in there and stop it from spinnng. Maybe it would hold up to a constant barrage of water, but with the salty roads we get here I wouldn’t want to try it, unless I could protect it.
 
I installed my ARB Duel compressor on the SLEE mount a couple of years ago along with the SLEE accessory mount (still unused). Compressor rocks as advertised!
 
For those using the SDHQ mount, does the extra hose they provide eliminate the need for the manifold kit when using the compressor to air up tires, or does the hose still get wicked hot?
 
Ok so I went with the SDHQ mount because I don't need a manifold and it comes with an extension line as ARB recommends. Also no drilling to make it all fit. It was kind of a PITA to install though so I hope to never need access to that fuse block underneath it. I do like the Slee design better where the accessory tray drops into the mounting brackets, but whatever.

So it's in, but I don't really have a need for the ARB air compressor switch in my cabin, since I'm not using air lockers. The ARB compressor comes with a fairly complicated set of switch wire harnesses which I don't really need (#2 in the diagram below). I'm thinking of just putting a waterproof/marine grade on-off switch in the engine bay next to the compressor and just flipping that on when I need to air up. Anyone else done this? I *think* I just need to wire the purple (+) and black (-) to either end of the on/off switch, though I'm wondering if the ARB switch actually has a tony relay inside it? Bonus points if anyone knows where to get that 3-pin waterproof fitting used in harness #2 (second photo) so that I can just create a new one rather than cutting this one (even though I'll likely never use the ARB harness).

I could spend the time fishing this whole thing into the cabin and finding a place to mount the ARB on/off switch, but why? (Note that ARB actually shows someone wiring the switch under the hood, but the instructions specifically say to keep it away from anywhere that could get wet, including the kick panels inside the cabin, so this seems like a terrible idea).

Update: I found this diagram on tacomaworld which seems like it's the simplified version I'd like to do. Anyone see any issues with this?

The ARB switch has a light... which is kinda nice. And switched is fine too since your engine should be running when using this compressor anyway. Or maybe, a simple switch like you propose and a hood with an auto on light would be better.

Yeah. I don’t have a place to put the switch inside the cabin, so to use it I’d either need to wire it in the engine bay (which seems like it won’t hold up) or cut a hole in the dash to fit it.
 
I wired mine for a while like the second diagram. Most of that original harness is coiled up under the compressor near the air switches.

My first install was uber fancy and had a physical override switch under the hood, and a bluetooth relay in line. So 99% of the time I could trigger it remotely via bluetooth on my phone, and if I was under the hood already I could push the button. I did this as my initial install had an air tank and rear bumper air exit, so I wasn't up front when I was 'using' air.

All that is gone now and I've got an underhood air exit, and in cab physical switch. I do miss the rear bumper access. My fancy teflon and steel braided hose eventually wore thru from rub friction - needed less sharp corners and more affixing points.

No issues for me in a few years with the ARB switch in the designated spot on the slee bracket.

Interesting I didn’t realize the Slee bracket had a spot for the switch. Huh. Maybe I’ll just mount it and see it it holds up…
 
When not using the "Manifold" keep a close eye on the hose temps right at the connection.

I had 2 pop off (melt/heat) before i added the manifold to my setup in my other truck. I had no other use for the manifold other than to dissipate the heat, and its worked perfectly for that for 3 years solid.

Were you filling right at the compressor with the quick connect directly on the compressor, or did you have an extension kit? ARB does say to either use a manifold or to use their Remote Hose Coupling Kit. The SDHQ kit comes with the 90* elbows and about 15" of air line, so I installed that with the ARB quick connect at the end of it.

I guess if I have issues I'll look for a manifold kit but I hate to drop $90 since I don't have any other reason for it.

I was filling right off the compressor, which I 0/10 do not recommend. That SDHQ kit should work, provided its a good quality preferably braided length of hose.

The connector you need is Automotive Connectors CON MP 150 3W FEM ASY (Fully Assembled); got mine on e-bay.

I wired the provided ARB switch under the hood and installed on the Slee tray. No problems, good location and access. I did wired a parallel trigger wire through the firewall to turn the compressor on, but didn't use it. I also have the AirLift wireless controller wired in and mounted under the hood for the rear air bags.
 
Did anyone see ARB came out with a fully brushless version of the single and dual compressor at SEMA? I wonder how much temps will differ..

Yes! Also very curious regarding noise level
 
Finally saw an actual ad for the new dual brusheless

They’re claiming 50% increases in output 🤯

Also, now has a cooling system:


Disclaimer: I’ll still use my M18 Milwaukee for airing up duties though. Just passing along Info
