Pulled the wiring harness from my fifth wheel

Was parking it after the weekend getaway and it got caught on the tailgate. Pulled it completely out of the junction box. Got the lights all working but the trailer brakes still aren’t functioning. I’ve searched the web and can’t find solutions so alas I’ve come here. I have the 12v+ from the truck to the 12v+ on the trailer and the 12v- and all the white wires to the 12v- to the trailer. Best I can tell all whites should be neutral. I have the blue trailer brake wire to what I can only assume is the rv’s trailer brake wire because it was the only colored wire not used (it was blue too). The break away switch has two wires. One I spliced in with the blue wires and the other I ran to a wire that runs directly from the rv battery.

When I first started my truck would acknowledge the trailer was hooked up but was giving me a “service trailer brake”. The way I have it now my truck isn’t acknowledging the brakes but lights work. No output from the control when manually operating brakes from control.

Any solutions?
