Spare connector under left rear?

[ZJ2UZJ100]

While under the truck today, (wife says she hears an annoying clank...I'll take any excuse to get under the truck...) I noticed there's a spare 12-pin electrical connector at the left rear. It's hanging down next to the very last body/frame bolt/bushing. It splices into a cable bundle that comes out of the left rear quarter panel through a weather-tite seal and heads over the spare tire to the other side.

The connector was exposed and slightly corroded (green powder) on one of the pins. It had lots of sand packed in it. I cleaned it up a bit. I am wondering if there's some feature that uses that connector that I might need some day.

My guess is it might be a different attach point for a 7 or 12-pin trailer wire connector, instead of the 4 pin connector that comes stock.

Any other ideas?

It's actually not dangling.

It's mounted to a plastic clip to keep it in place. There's space for another connector on the clip that is not presently used.

Also recalling that not all 12 pins were in the connector. Maybe only around 5 or 6?

Sounds like the trailer harness....

I'll take a guess at where the rear locker plugs in, my 03 has this connector and also had a number on the harness which I traced thru epc to original factory locker wiring.

Oh BTW, my trailer harness plugs in on the RHS

Rear Locker control makes sense.

If it is actually an electronic locker (?) or maybe if the electrical switch modulates an air valve back there for an air locker....I'm familiar with the construction of a locker inside the diff, but not the controls.


My 4pin trailer wire harness (seems to be working fine) is probably also plugged in over on the right underside.

Where I am looking at this bundle coming out of the left rear fender, there is also another strange cable or tube that is clipped off and capped. It's a plastic coated tube that could be either a pressure line, or some kind of low-gauge conductor....Trailer brake wire?

I'll try to get a pic to make it easier to explain.

If you pull the cap off the "strange cable" you will see it is a heavy plastic tube that runs up behind the inside left panel, I presume it was used to run a wire cable in to activate the fuel release flap when the manual pull cable release was inplace before the electric one. Remember these wiring harnesses cover all model variations in the world AFAIK.

I have a manual fuel release cable.

Here's a pic...
