Dear Forum, I need some help!

[GulfCoastJT]

Ok, so I’m in need of ya’ll’s knowledge. So I was taking my drivers door off of my ‘20 JT. When I removed the drivers door access panel for the wiring harness and I saw a plug hanging there. So could someone please Educate me and tell me what does this go to?
thanks in advance!

Just checked the wife lady’s 2019 JLUS. She has everything on her doos except keyless entry. There is no plug like that.

i looked this AM, and i may have the same cord, but it is tucked way underneath and heads to the firewall. I have an Overland with lots of options.

Book says gray 4 pin connector under dash to left of brake pedal.

Yep. Except this is what my brake controller receptacle looks like:

And this is black, not gray and looks more like It will receive this:

Though I have also seen brake controllers that have ends matching up to the OP’s picture.

Man, I LOVE the internet!

This video showed me I need to look behind what I thought was my brake controller:

That is the OBDII diagnostic port. AKA where you plug in a scan tool.
