Howdy everyone! The OEM trailer brake controller plug looks like to be cut off from my truck. Wanting to know which wires are what so I can add a brake controller. The wires I’m referring to are under the dash. Ive got a 1) big solid blue. 2) blue/white. 3) green/black. 4) white/red

It’s an 03 Ram 1500 Laramie w/ towing
Thanks!
