AUX Switches: Cable COLOR CODE Wiring Identification

[Theweda123]

Hello all,
I’m needing some help!
I wired up feniex fusion-s 800 light stick to the aux2 switch and the converter box that came with it to the accessory wire as it needed 2 different power sources and I get power coming from my vehicle (2020 Jeep Wrangler JL) to the converter but there is no power coming back out of the converter. I have tested it with a 12v tester and all the red wires and mode (white wires coming from converter) wires have power but when I test the data wires going back to the bar I get nothing. Anyone done anything like this or have a idea on how to get the lightstick to light up?!?
All I was given was picture directions (Pics 1 and 3). Picture 2 is how I have it wired. I plan on heat shrinking the connections when I get it to work so it cleans up nicer but for now I’m using these connectors.

Update: after talking to my local light bar gurus and still no success I contacted Feniex by their chat and they had me send them my converter and they sent me a new and now it lights up. I was also able to wire all the red together and all the black together

I've just started wiring things to the Jeep/Aux ports and I'm really suprised at how thin the wiring is for the aux lines. I put some foglights on with 14g (maybe 16g) wire and it's way bigger than the 15amp aux (3) I plugged it into.

I planned on wiring more things to those wires, an arb compressor, etc. But they're such small gauge. Especially the lines directly to the battery, I thought I'd wire a bunch of things to that. Am I going to create some fire hazard by wiring multiple things into the direct battery line? Do I need to replace it with a larger cable? Or do I just need to stay under the fuse amperage and I'm overthinking this?

New to electrical stuff

I also noticed it was like 18g wire. What I did and idk if it’s right or wrong but it worked for me cuz I also had a similar issue. I connected the aux wire 18g with a 16g wire using a butt connector then I would then have a pigtail of the 16g wire to connect what I needed. I had to connect multiple wires twisted together in one butt connector. So that was my solve. I’m not a big wire guru so I can’t really tell you yes or no on the fire hazard. This is just how I made it work for me.

I had some trouble following this colour code this past summer and I brought my Jeep to the dealership to check it out. Turns out they have changed a couple colours on my 2022!

In my Jeep, Pink / Orange Stripe is Ignition and AUX 3 is Orange / Pink stripe. This is backwards from the diagram and led me to think my ignition wire wasn't working!

Hopefully this saves someone some time or money.
I got the following sheet from my dealer showing me the 2022 wire colours:

*Edit - It seems like some replies here show the correct colours but the original post has the colours for Aux 3 and Ignition switched.. Cost me $300! I should have tested them all, but I figured I had some things wired in and working correctly so there must be an issue with the Jeep! Is the OP still around to edit this?

As posted a few times earlier in this thread and also in your post the color coding is as in this pic:

Clearly I thought I did read the whole thread. What wasn't so obvious was that one colour was swapped and in error as most colours were the same and appeared to match. The OP has now updated to put this note above the image which should help others. Hopefully this update and my request to the OP to update the first post helps others, unlike your attitude : ) (I can also bold and underline).

The colors aren't as obvious as in the photo too. Hard to tell the colors (colours) apart on my Jeep anyhow. Don't take the other answer personal, he can be a little demeaning, but usually has good info.

Sorry, but a stickied post should not require detailed reading of 14 pages of posts for such a fundamental thing.

The OP apparently updated it a few days ago indicating that a couple wires might be inverted. I would expect that a stickied post would have been verified and corrected.

And yes, I made the same mistake in assuming that a stickied post would be accurate.

Amen to that. RTFM anyone?

After a few installs, I have cut off everything and made a DIY harness with weatherproof plugs to make my life easier as I did quite a few swaps in the past year with the jeep in regar to connections to my Aux switches

now when needed, I can swap around the light configuration easier. I usually have a summer and a winter config. With more night wheeling in the winter, I have different lights that I don’t use in the summer, which I have more of a camping light configuration on the platform and back of jeep to accommodate camping needs.

now the wiresstay the same, I just switch the connectors!

8/12/21 Update .... Must Read...
IMPORTANT: Do know that if your JL/JLU has Aux switches that were installed at home, a shop or at the dealer and not at the factory, that you need to read at the links below....

Read at the links directly below.... then read the rest of the posts in this thread.

Mine being aftermarket install, where are the fuses to check and see is they put in the correct ones? thanks so much.

Hi all -

First time I can actually add value to a post on the forum

I had the Mopar Auxiliary Switch Bank added to my 2018 JL about 6 months ago via the dealer. My set up is exactly the same as @zyt had described above with Aux 1 & 3 rated for 40 amps, 2 & 4 at 15 amps.

Since having the switch bank installed, I've added some auxiliary lights. In doing so, I can also confirm that the 40amp wires are larger diameter vs the 15amp wires. To be fair though, I've only used the 2 15 amp switches to date and have not tested anything on the 40amp connections (Aux 1 & 3) yet.

Picture doesn't do a great job showing the difference -

(Edited for wire color/switch clarity)
Orange - Aux 1
Purple - Aux 2
White - Aux 3
Grey - Aux 4

Hope that helps

Would you know where the fuses are located for these wires? I sure would like to check mine. I was told that 1 and 2 are the 40 AMP and 3 and 4 the 15 AMP. Thanks.

On the back firewall of your JL you will find what you see in each pic.... those pertain to your non factory installed Aux kit..

Hi all Aux Switch Grurus- @Rhinebeck01 and a few others, question for your all:
It seems everything I've read here suggest Aux 1 & 2 are for 40 amps and Aux 3 & 4 are for 15 amps. I believe this is true for factory installed options.
What about the mopar switches (82215190AE) that can be purchased afterward? I installed those myself and Mopar instruction shows that Aux 1 & 3 are rated for 40 amps, 2 & 4 are 15 amps. I confirmed this on my jeep by checking the actual fuse starting from passenger side, and they are in fact 40A=>15A=>40A=> 15A. I assume the picture accurately labeled the order of Aux switch 3=>4=>1=>2.

Anyone know if this is accurate? I've searched quite a bit here, but it seems everyone is saying aux 1&2 are 40A, and 3&4 are 15A
