What are these wires?

2020 2500 Tradesman, regular cab, bare bones config.

I just bought this, and am looking at upgrading several things and trying to figure out what I have. Anyone able to give me any info re these wires under the dash? Picture is looking at the right sight of the space after you remove the main kick panel.

#1 - three wire plug that is attached to steel framing, awaiting some feature.
#2 - a tap that the PO installed on that yellow/green wire that goes into that big connector. Just wondering what that wire might have been for, anyone know what the connector is for and where I can find the pinout for it?

1- aux 2 trailer camera input connector

2- trailer brake controller. The pink/green tapped wire is ignition run power. The green/white tapped wire is brake signal.

Thanks! I wonder why the previous owner needed a brake controller when the truck had that option installed at the factory?

I meant that those connectors you circled are plugged into the factory brake controller module.

I misunderstood, thanks for clarifying. So the previous owner was doing something up front with the brake signal. I can see some screw holes in the trim below the upfitter switches, maybe those were related. I'll probably never know, but I have a general sense now. Thanks again!

I was hoping to find the connector for the temp sensor waiting for me when I took the panel off, as some folks have said that Tradesman 2500 usually had those harnesses present even if unused. No such luck.
