Wiring power for Onboard Air ?

[jackvz]

How are you all wiring power for an onboard air compressor? Using the Aux switches/ wiring harnesses isn’t possible as they are only rated for a few amps only when for example a dual ARB pulls around 30amps.

I have an ARB dual burshless under the hood using the zroadz install kit. It's directly wired to the battery for primary power, and I used an aftermarket square OEM Toyota-style switch. A jumper from TacomaBob to power the backlight for the switch and to avoid tapping into factory wiring.

I really wish the zroadz or someone else could find a way to get a compressor under the hood on the hybrid. I really don't want to mount it in the bed or carry a portable compressor.

Wired to battery. Use AUX 3 to turn on.

Did you mount that inside the bed space, behind that plate below the outlet box?

Wired to the battery using the zroadz bracket and wired directly to the battery. It took the time to fish the power wire up with the main harness so I didn't have to notch the fuse box. I left the power switch on the bracket.Because I have to hook uI left the power switch on the bracket, because I have to hook the airline up anyway.

I use AUX 1 and a relay switch for my single ARB

. Easy peasy.

Thanks for posting. I was thinking of a similar reel install. What mounting bracket did you use specifically?

You use the aux1 harness to power? What is the relay switch for?

So... the Aux1 turns the relay switch on and off, which supplies power to the compressor directly from the battery.

Gotcha! I have a hybrid so need to find a way to run wiring to the battery under the backseat

Don't they have a hot stud on the fuse box under the hood?

There is indeed but I don’t feel that is the right place to permanently hook up an accessory that draws 30-40amps.

That's a ton. Good idea.

Stock ARB Brushless mount and an aluminum plate on the backside.
