re: Pulled the wiring harness from my fifth wheel

Yes, it's just your typical metal junction box where the wiring harness from the camper connects to all the wires within the camper.
Is there a way to test the brakes with a multimeter? I know you can have someone push the brakes and listen for the magnets to activate but I'll be solo on most of this.
Also my truck was registering when I hooked the rv up but after I rewired some stuff it's no longer doing so. Makes me think it's a wiring problem and not a wire being pulled loose. I'm just at a loss because with the lights working there's literally nothing else to wire up so it has to be wires connected wrong but every diagram I've seen has it the way mine is.

Connecting Electrical Braking Wire at Trailer Junction Electrical Box.
First response suggests
Eta maybe try swapping the break away wires.

I read something about pulling the pin in the break away switch. That should apply full available voltage from the trailer battery to the brakes. If the brakes are locked up then that narrows the issue down to somewhere between the switch and your truck.
Eta it could also be the actual plug. Also reading that those plugs are sketchy. It could’ve been damaged enough to not get a good connection when plugged into your truck.

This sounds like a ground. Its basically what recognizes that a trailer has been connected. I know that's how it works on GM. And I also believe if it doesn't recognize a trailer connected, the brake control doesn't activate. Also, if its wired correctly and the battery on the trailer is good, you should be able to pull the break away and the brakes should lock, even not connected to the truck. They usually sound like a buzz at the wheels
Push come to shove, you could always buy an aftermarket controller and wire it in. They're stupid simple.

Make a jumper to jump whatever pin to ground in the plug and check for continuity on the other end to see what pin the wires go to in the plug.
