Howdy SCM,
Do you have a house power system? If I understand you correctly, you want to power the compressor with a system that can function without the engine being on. |
Exactly. I do have a house power system.
It sounds like you guys are using the "isolation switch" wiring to connect to your outside, illuminated switch. What I would like to do is take the red-yel wire that's shown going to the ignition switch in the wiring diagram, and instead run that to an on/off switch then to my house battery.
Is there any reason that wouldn't work?

I think that's what I did--trying to use as much of the existing wiring as possible. Give it a shot!

Bump.
I can't answer your questions PDX but I do have more to add/ask on this topic...
Here's where I put my compressor. It takes up no space that we would be using otherwise and I can still access the filter (probably need to every 15 years). It was a major hassle to install it here and I even paid to have a bracket welded up.
I followed the ARB instructions to a "T" and I'm thinking I want to change that. If I recall correctly, the supplied "Compressor" switch triggers the compressor - not the relay. The other wires, that ARB says to connect to switched power (and the relay), I have going to my blue alternator wire under the driver's seat.
That works great but I need to have the engine running if I want to use the compressor. That's exactly what I want if I'm inflating a car tire BUT annoying if I just want to top off a mountain bike tire.
So, I'm considering another place for the "switched power" switch, Having a little switch under the air connection flap looks like a great idea. But where to "T" into power there? |
How is this location working for u? How are the noise levels? Also is there enough airflow in there. I am thinking of mounting mine in here as well.

The noise is very little. You hear it, but it's muffled and far less noisy than the engine. I think it's kind of a mute point though, no one is running their compressor while trying sleep are they?
As for air flow, until a few days ago I would have said that's another non-issue. The cabinets are far from air tight, and it draws air from them as well as the space between the body panels. I've run it for about 10 minutes at a time while inflating my van's tires from 40 to 50 PSI and my neighbor's 4Runner tire from totally flat to 40 psi without any problems. BUT, the night before T-giving I was airing up the winter tires on my wife's car and I just couldn't get the last one up from 30 to 35 psi. Not sure if the problem was with the compressor or my air nozzle.

The wiring loom and hose easily goes through the hole in the back panel of this space. For the wiring as I mentioned I ran the 3 wires that connect to the battery:
back through under the bench to an aux battery that I have back there.

For the wiring I used the red, red-yel and blk wires that were connected to the isolation switch to connect to the 3 prongs on the illuminated switch:
The red-yel wire (that's supposed to go to the ignition wire) I then ran to the cabinet under the sink where I have a fuse panel that connects all aux powered components to a switch that switches my 2 aux batteries.

Here's a few pics of the front and back of the hookup box:

Great thread, thanks again Kourt! |
Are you sure that this hookup is correct? i tried the same setup and (red/yellow to +12Volt) but when the blue switch is in "off" position that the cable gets really hot. This only works if the blue switch is on and lighted. Any other you cable you hocked up? |

For those using the gowesty hookup box for this....
How the heck do you disconnect the air hose when youre done using it?? I have to stick a screwdriver or a knife in there to push the quick release. Theres no way my fat fingers are reaching that deep. Am I missing something??

I had the same problem but got lucky to talk to Lucas from Gowesty at the last Syncrofest. The connector is a push pull design and needs to be very loose installed. I had mine behind the fridge and when pushed it it was not moving and disconnect did not work well. If the outside hose is connected make sure you still can move the hose connector. When finish, you only pull on the hose and it will release (if installed correct) |

That's right--you must have some play in the connector at the installation point. It is push in, pull out. It's designed to not require depressing the receiver for disconnection.

Thanks y’all. So basically this whole time I’ve been screwing with this thing to disconnect the air hose all I needed to do was just pull it. Thanks for helping me figure it out!!

I just did a dry run of my install that will be similar to this. I connected the red/yellow wire to the positive terminal and promptly burned through the diode inline with that wire. Anyone have really clear instructions on what to do with the red/yellow signal wire? Must i contact ARB for another diode if not connecting to the ignition? I would like the compressor to turn on whenever i want via two switches like the original poster. A master switch and another switch accessible from hookup box. It will be connected to my auxiliary battery.

I'll try to find some time to pull my fridge this weekend and document the wiring. It seems that is a consistent problem coming up in this thread. Stay tuned.

That would be awesome, Kourt!
Anyone know what kind of diode i would be looking for to replace the one that went up in smoke? I checked ARB documentation and it wasn't listed (from what i saw) and messages to ARB have gone unanswered.

I talked to ARB USA "tech department" and they did not have any documentation on what the diode was. Which i find very funny. They could only give me a parts replacement number for that entire section of the harness (180415).
Anyway, since i am not connecting to my ignition circuit and instead directly to my Auxiliary battery, i will go without the diode. However, i will include a fuse.
As far as the rest of the installation goes - Interested to see exactly how Kourt wired his or if any others can share. mreuter had the same problem as i am having with wires getting hot. With all this Covid 19 craziness, its a good time to disappear into the garage.

Just an update: my weekend filled up, so taking the galley apart to view the wiring is not in the cards, but I found a few references to "ARB compressor wiring" in google searches that show there is a palpable demand for a simplified wiring of this compressor.
I'm pretty sure I followed this guide on one of the Tacoma forums:
https://www.tacomaworld.com/threads/arb-ckma12-simple-wiring.496055/
Have a look at that--I hope it helps. My install is just a compressor direct wired to the DC mains by way of the relay, with no solenoids.

I am ready to wrap this same project up as well, as I have everything mounted, and finishing up the wiring just now.
I noticed in the photo above on the isolation switch mounted in the hookup from top to bottom it looks like RED, RED/YEL, BLK.
Shouldn't it be top to bottom RED/YEL, RED, BLK, as the RED/YEL is your 12v source for the toggle switch (connecting pins 2&3 on schematic) , and connects the 12v to the "closed" pressure switch on the compressor, then to #86 (BLU) pin on the relay, then to #85 (BLK) pin (ground), in turn closing the switch in the relay (#30 RED & # 87 RED/WHT) and then turning the pump motor on?
Also,
In Kourt's TacomaWorld link above, this is how it is wired as well, with 12v (RED/YEL) wire going to the #2 contact on the schematic and the #3 contact going to the pressure switch.
Some photos for reference:
(keep in mind the #'s on the 3 prong switch do not correlate with the #'s on 5 prong switch)

Finished the project last night. Compressor is running perfect, no hot wires or blown diodes (top to bottom on isolation switch= RED/YEL, RED, BLK{or other way around bottom to top if your isolation switch is flipped 180*}).
I deleted the fuse and opted for a marine grade Bussmann 40a CB that I can also use as a master switch that renders the isolation switch in the outside box useless if I have the CB "open", and it still provides the circuit protection when "closed".
I also connected the RED/YEL wire for the isolation switch to the #30 pin (RED) on the relay (just put the wires in the female slot and inserted the relay ontop) this way there is only power going to the isolation switch when the CB is "closed".
Thanks to Kourt for the idea of putting the isolation switch in the hookup box. Love this idea.
Ben
