hello everyone, I was wondering if anybody ever figured out the problem with the TBC module on mid-2003-2007 ford super-duty, I've read numerous articles on wiring, brake 7-pin connecter and so on. I was wondering if the problem is in the module itself or in the grounding of the plug when you connect the trailer to the truck. I heard so many theories I'm confused on trying to sort out the wiring aspect or just get another module to put in. A 400.00 module you can not return to the dealership. Any help would be appreciated.
