Zroadz bracket kit for tacoma fits as the 4runner is the same body wise for alot of things. The kit is great and comes with almost everything needed to install. The instructions are excellent with pics! It comes with the printed instructions so you don't have to print it from their website. The process is mostly the same for the brushless compressor install except the bracket part. The mounting holes pretty much line up. Its not perfect but it will work if using the bolts with the bracket kit. I had mounted the compressor bracket and air attachment to the zroadz bracket before install to make things easier. You will need to loosen the 2 Allen screws on the compressor bracket to be able to slide the compressor in and out. You will tighten the Allen screws after you slide the compressor down after the bracket is mounted with your compressor fittings set.

You will need the ARB air up kit as stated in the instructions unless you were to piece out each component.

This is how I set up my pressure switch and line to the quick connector.

The hardest part is the wiring and I used a fuse tap to the drivers side fuse box for the ignition signal. I used the blank S/HTR 15a slot on my TRD ORP as its capable to handle the amperage. I used a 7.5s fuse in the fuse holder which is close enough to the 8a that it says in the instructions.

You can slide up the harness to the fuse box and remove the cover to the wire loom. I put the wires through the loom and into the fusebox.

I took the ARB harness and made it my own removing the unused wires and made it to length for my install. I am not running additional lockers so I am just using the isolation switch side of the wiring. I also used cable loom like the factory harness and used 3m electrical tape around the loom to make it look like factory.

The ground I used the bolts to the bracket which attaches to the fender side. The power I ran to the battery terminal. I secured the harness with cable ties.

The hood propt is too long on the bottom side and hits the body when put up into the hood. I had to grind down the end and paint it to prevent it from rusting. Other than that it works. You will not need it though if you have hood struts.

Overall very pleased with the setup. Just need to add an air to water separator cause I did notice moisture does get created in the lines when using for a while. Also if you don't know but the compressor and air fitting closest to the compressor does get burning hot!

Nice work! Question do you have the factory Aux switches and if so are you using the 40a “switch 1” for this?

No I do not have the auxiliary switches. I just used the ARB switch in the spot for the switch on the bracket. Its simple enough to keep the wiring all there and your gonna be next to the compressor anyways. You can tell if you accidentally left the switch on as the compressor is loud.

yeah I have a high output “non brushless” ARB from my JKU. Been waiting for someone to come up with a decent bracket for it so that I can get it mounted up in my Pro

BulletProofFabricating make one for the ARB twin canister for the same location.

https://www.bpfabricating.com/produ...compressor-mount?_pos=10&_sid=1b4907238&_ss=r

I seen that one but I liked the zroadz one better as it looks more solid how the bracket mounts at the radiator support and has the switch and connector hole as I'm not using the external manifold. Also came with the hood propt rod.the zroadz bracket also can mount a dual compressor but I have not tried a brushless dual but im quite sure you could make it work also if the holes didnt line up by drilling new holes.

I see.

zroadz state it does not fit the hybrid model.
Wonder if that is strictly on Tacomas or same with 4Runner.
Curious what is the difference there.

BFG one fits on the 4R hybrid.
Im not sure i can try see if there's any difference. But if it fits a tacoma im quite sure it will work on the runner. The zroadz site says fits only tacoma but it does fit the runner.

Just curious as we get really cold weather and don't want the condensation in the line when filling tires mid winter?

Sorry trying to catch up on the thread. So you have a link for the “BFG mount”

Update. Got an air to water separator, orange 1/4in 10ft hose, and black fitting kit from Amazon to add to the ARB hose. Connected the filter between the hoses. The ARB hose is a little on the shorter side foe the runner. I would like it to have more slack and not rub on the fender or anything while trying to reach the back area so the extention I think will be good. Also its an easier way to add the filter so its not too close to the compressor where it will heat up alot. I could attach the filter after the hoses but didnt like the extra bulk at the end and I dont want to put to much flex on the filter as I see its plastic and there is a seam in the middle.

You are more talented than I with wires. I'd be concerned about screwing it all up.

Thanks but its not that bad once you get rid of all the unused wires. The hardest part was unwrapping the electrical tape off the ARB harness cause there is a pcboard and diodes as shown in the wiring diagram from ARB.

Very nice write up! Here is my install video in case this can add to the help. I installed in same location but with only the included Arb bracket and I installed to one of my Aux switches. I detail
aux switch wiring,

the ports on the compressor for pressure switch, quick connect and pressure relief valve,

Arb wiring to Aux switch in depth

the Oem in board air location in depth and why I installed in engine bay vs there
