Anyone know the diagram for the factory brake contoller harness on 2001 3500? I know what the colors for the brake controller are but my factory harness wires are not labeled.....

 

Welcome to DF

Someone cut the ends off under the dash did they? because that's supposed to be a plug and play thing.

Anyway you can find the wiring dia in the 2001 fsm found here, under sec 8W54
