I just purchased a 2026 Ram 1500 Bighorn. Came with tow haul and a 7 pin plug on the bumper. It did not come with the control for the electric break. After the dealer tried to rip me off just to tell me if the plug is behind the display I've turned to doing research on my own. Any help would be appreaciated on how to know if I can just add the break module and what to use. TIA
