rear wiring diagram?

[Rolling18]

Greetings GuRu's

My 4 dr. Wrangler was in a multi-roll over destroying the hard top and tailgate.

As a result, a few things dont work likely due to damaged wiring.
Rear Camera (replaced still inop)
Rear Wiper (replaced / INop)
Rear washer (replaced Inop)
Left driver side power mirror (replaced still InOp)

Oddly, rear defrost works!
no airbags deployed.

All fuses and relays are good / well seated in TIPM

I'm needing to know if someone has a source for rear wiring harness or find out what wires all these have in common and location.
this is just a "driveway rebuild" so no dealer support.

thanks for any assistance!

I’m sure that anyone with info will need the year model of your Jeep.
Also, with a rollover, have you had the frame checked?

You're going to need factory wiring diagrams for all those circuits and begin diagnosing them individually. None of these really share anything.

I'd suggest taking it to a dealer and having them start from scratch, it's a lot of wiring to trace down. Worst case you're running overlays.

Not so fast. They all run down the driver's side. My guess is you cut a harness or snatched out a ground crimp. Most likely a ground though. Cutting a harness would typically blow the fuses on the cut wires. I would start at the mirror. Check the plug. Trace it back until to find the issue. Should be relatively easy if they are all related. God ble you and the gremlins if each problem is a unique fault.

I’m guessing you already have looked at the wiring diagrams and connector locations here?

I think @alphawolff means other than being bundled together into a harness, they don’t share a lot of commonality. IDK.

in JL wrangler forums kinda thought that was self explanatory? hehe.. 2022 4 dr. (as in signature) and yes frame is definatly tweaked, one reason it was "totaled" but still drives straight just sits a little uneven soon to be fixed.

Yeah, I mean they don't share circuits. It could be totally unrelated faults or a common area for the damaged body harness. Diagnose one and you may fix the others in the process. They state the mirror doesn't work, which isn't anywhere near the rear and I'm not sure if it even goes to the body harness, pretty sure it connects right to the instrument panel harness.

That totaly makes sense! and blown fuses would that out the whole item not just part like power mirrors only working on one side and working items sharing same fusees as non working.

I did manage to find the wiring diagrams on here last night and downloaded i just dont know how to read them very well.
also makes sence to check the mirror first as its closest to the engine compartment closest up stream (if all related)

not sure what a "ground crimp" would look like though... hmm
thanks for the insight!

yes that what I am thinking / hoping for is one fix corrects all or more thAn one item.
im thinking the mirror harness intersects or shares something with the other problems under the hood.
