Attention: TDR Forum Junkies There are no instructions for the factory installed brake controller. Any help on setting it up. The dealership was a little vague in its instructions. My old controller I just moved the plus button until the trailer would stop the truck from approx. 10 mph with out using truck brake. Dealer said get truck to 10mph and move the slider to stop truck and what ever controller reads use the plus or minus buttons to get that reading. Need help as we leave in a few days
