Re: AUX Switches: Cable COLOR CODE Identification
Today we installed a lighted whip on the back of the Jeep (mounted it on the tire carrier, relocation bracket / mount).
After much research we wanted to help and/or save others time finding and identifying the AUX cables.

Here is a short video and photo showing the wiring color codes and where to find them to install your Jeep accessories, which will work with your AUX switches.

The interior AUX cables / wires are located inside front passengers side footwell area or foot kick plate area (which the video will show).

I'm not pre-wired for aux switches, but the color coded wires will help. I don't see a ground wire. What did you use to ground your accessory?

@msujedi

IF you do not have Aux Switches installed on your JL, how will > "color coded wires will help" ?

Now, you want to know where to ground... are we talking a ground point in the passenger foot well or in the engine compartment?

Here is a ground point in the engine bay by the main battery. Look at where finger points in the pic:

In this pic, you will see a grounding point in the passenger footwell:

Nice. Your pic is exactly what I was looking at on my JL. I thought that bolt with a nut & nothing on it could be a ground point. But, I also found a 'loose' black wire hanging out just above and forward of that ground bolt.

I should be able to butt my negative wire to the black 'shoelace' rather than to the ground bolt. Right?

Do you know what that wire is for? I would not assume it is a grounding wire. Did you take the plastic off and unwrap the black tape to see what color you have there? Maybe test with one of those volt meter?
I would ground to the bolt as someone said above.

Personally, My accessory (color whip), we were able to ground to a bolt where the other wires come from, by the hinge coming from the back gate/door (by where the backup camera wires are located).

I ended up grounding to a bolt. But, the more I looked around under the dash the more non-terminating wires and plugs I found. Just makes me wonder what they're for. The one I was holding had black rubber insulation. The tape stopped an inch from the end. If I get around to finding out what the various wires & plugs are for, I'll post the info.

In the first pic, #3 and #5 color descriptions don't match the pic. Which is correct?

Appreciate the info. Watching for updates on how others use the Aux Switches.
Question: I’m thinking of adding a USB port under the dash. (Want to hard wire my phone charger in). Assuming I can just use the direct to battery since I want it always on. Any concerns with tapping into this?
