Aux switch wire

[BambiBasher]

Was doing some wiring for my factory aux switches. Then I came across this little guy on the right. I was hoping for a ground but I have a feeling I can’t be that lucky what’s it for?

I’d say it probably is, just unused. That’s how the aux wires look under the hood from the factory, with a little rubber cover. Probably an option that mounts in that area somewhere?

Follow it. See where it goes. Maybe you’ve got a Flux Capacitor!!!!

Those are factory installed aux switch wiring. The owners manual shows in cabin and engine bay option.

The manual says nothing about the wire the OP is referring to.

Oh sorry, just saw the lone wire on the right.

I have the same wire on all of my Jeeps. It's curved back into the larger group of wires and taped. I'll need a garden gnome to follow the wire though.

Ya know I think I saw that one too when I was ripping things apart one day. Due to the shape I thought it might be a vent of some sort. I didn’t look too closely at it since it wasn’t my purpose for being down there. Learned long ago that if you go exploring in a Jeep because it could lead to many rabbit holes so I just keep on task and save those for other days when I don’t have a purpose in that area.

That is interesting if it is not one of the aux wires. It seems a strange place to terminate a ground wire unless it is used for an option that is not selected and is already in the harness. I usually ground any additions near the item instead of wasting the effort to run a ground wire back to one of the lugs or the power distribution with the exception of the winch due to the amperage. If i wanted to use it for something I would check if it has voltage when off/ running or the aux switches are on etc and if not check for continuity to ground but it would be just as easy to add a ring terminal to what you are powering's ground wire and use the ground lugs.

I found posts going back to 2018 on the JL side talking about that extra wire but with no info of what it is for.
