Wiring Portable ARB compressor to Aux button??

[Tech Tim]

That's brilliant! Perfectely understood. That was really hepful, thank you! Quick last ones: would the new wire thickness matter? I presume it would be ok if it was the same as the red wire from the Grimm kit harness.

Just for confirmation, I assume that since this wire should go from the ARB button (which is a low amperage), it will have to be connected to either of the wires corresponding to either aux switch 3 or 4, correct?

Also after running this setup, is there any fuse which needs to be changed in the Jeep fuse box?

Thanks again for your time and valuable info provided!

A 16 gauge wire should be sufficient.

Yes, connect to switch 3 or 4.

Don't need to change any fuses.

Super! Thank you!

No problem using the 40 amp aux circuit, with up to a 55/60 amp load per most of the twin compressors??

Super! Thank you!

This is a great idea. I think I might save this as a future project. My switch under the hood feels a little loose, like hitting a bump could switch it on at any moment, so this is perfect.

The two fused, large-gauge, red wires on the ARB harness that carry high current for the compressor pistons should be connected directly to the battery. This thread primarily discusses connecting the factory Aux Switch wire to the small-gauge purple relay/trigger wire that carries less then 1 amp (the factory switch fuse should be adjusted to protect the small-gauge trigger wire).

I wondered ,thanks.

I plan to use one for my solenoid wire.

Im running 4ga to the battery Myself, I just wanted the clarification for future readers, searching the thread

Today I tried to install the Grimm Offroad compressor kit, and, surprise!! Although on both Northrige4x4 and Grimm Offroad websites it is stated that the mount is compatible with JL, the mount can NOT be used and it is totally useless on a 2024 Wrangler Rubicon 2.0L. More precisely, on the new 2024 Wrangler version there are 2 hoses that block the mount to be installed. Please see the attached image. I will file a ticket with both Northridge and Grimm Offroad. I think I am entitled for a compatible replacement or a refund for false advertisement.

You're in Romania? Is your JL a European version? Looks like your catalytic converter has some extra EU emissions regulation equipment.

Perhaps you're the first European with a 2024+ to order from Northridge, so you're the first to discover the issue.

Yes indeed, I'm in Romania, and I strongly believe that the love for Jeep Wrangler should not face any bounderies. I really love the Grimm Offroad product, it"s just that it would not fit on my European 2024 Rubicon JL, and I consider I should have been warned about it prior to my good faith purchase.

At any rate, I would love for Northridge/Grimm to come up with a solution just for the bracket itself. All other items included in the package are perfectly fine and fantastic quality.

@laurx, How are those hoses blocking the bracket? It bolts to the lower bolt on the master cylinder.

Do you have a pic showing the problem better?

@Tech Tim Yes, indeed, due to those hoses the compressor cannot be lifted enough in order to be bolted on the master cylinder. More precisely, the hoses can actually be forced (pulled) towards the left side (towards the front of the Jeep), however there's nothing you can do with the lower corner of the first hose (please see the encircled in the attached image), because the hose gets into the metal extension of the catalytic converter. So in order to clear that part, you will need to bend that metal extension, which is something I will not take the risk for, considering the price of a catalytic converter. And even if I had bent that extension, it would have still not be ok, as both hoses would stick to the compressor and would stay quite in tension.

Thus the kit cannot be installed, and therefore the entire kit is useless, let alone it was not the cheapest either...

I understand your frustration but obviously your Wrangler is not the same JL that rolls off the floor in Toledo, Ohio. With all of the foreign modifications that have been made to it, unfortunately you have to be happy with it stock or be willing to customize any parts that you buy for it that were designed for the U.S. version of the JL. Kudos to @Tech Tim for even responding to you and trying to help you after you threaten Northridge for false advertising, and the kit being useless, not the cheapest, etc.

I am not a technician, nor a Jeep parts developer, I can only asume that those who are know or are informed about different models throughout the world when they advertise compatibility. This is actually the first time it happened ever since I order Jeep parts from US, and I never had to customize any parts, as all I bought by now I bought for my 2.0 wrangler model and never had any issues.

And if you just carefully take the time to read my comments I did say that Grimm is an outstanding product, I would have really loved it to work on my Jeep. I can also add up the great support and brilliant intallation instructions (especially the video) from Northridge. I believe they are one of the best out there. This is actually the main reason I ordered directly from them.

And yes, since It does not fit my Jeep it is totally useless for me, and indeed it is not the cheapest.

Since Jeep is not sold in the US only, I think my experience should be seen by both Grimm and their dealers in order to perhaps properly inform future non-US and non-technial customers prior to their purchases, by stating on their site that this product is only compatible with US versions, just as I have seen on several other sites prior to purchasing other products, and thus preventing me from buying wrong parts.

No, no you are not. There is no way that you can expect Jeep aftermarket parts manufactures to know every modification that every country is in the world is going to make to vehicles that cross their borders. Show me in their advertising where they claim to be global compatible.

I can only asume that those who are know or are informed about different models throughout the world when they advertise compatibility.

Looks like you made an assumption, were wrong, and now expect someone else to pay for your mistake. Your comments are backhanded, passive-aggressive, and borderline slander.

Btw, does the RAR know that you are modifying your vehicle?

I’ve had a couple of “life lessons” when it comes to adding aftermarket parts and accessories or making assumptions. The first is to go through all the instructions and as many YouTube videos as I can find to familiarize myself with what the installation entails. Then actually look at my own Jeep to see if there is anything unusual about it that may cause interference of parts or other problems. I suspect if you (or the installer if that isn’t you) compared the engine compartment of your Jeep to the videos you wouldn’t have ordered the parts.

The other issue I’ve run into is buying two aftermarket parts from different manufacturers that ended up having interference with each other. I have front lower control arm skids and a front diff skid that interfere with each other requiring cutting and clearancing both parts.

I don’t think it’s realistic to think your circumstance could have been foreseen by a U.S. manufacturer or retailer. Or that U.S. manufacturers have access to Jeeps in every configuration from foreign countries. Just one person’s opinion which you didn’t ask for.
