Had the dealer set it up when i installed it so it would work with the computer. Now they tell me there is nothing wrong with it and the comp. knows how much brake to use. Any thoughts?
Mine is a 13, not a 12 but I connected my open car trailer while it was empty and the brakes worked fine except they were locking up when I pushed the brake pedal because of no load on the trailer. Even when it was set for 5 the trailer brakes were not on while driving down the road. I did set it to 1 and the brakes no longer locked up with the empty trailer. Later in May I will be pulling the trailer with a car on it so I'll see then but I don't think there will be a problem.
