I assume your F-150 does not have the Ford's brake controller (installed at the dealership)?
You are correct just the tow package and the Tekonsha P3 brake controller connects to the factory harness inside my truck. I have replaced the P3 brake controller already and have the same problem after installing the controller. I also dubbed checked the Tekonsha adapter used to connect the controller to the truck I went to their website and doublecheck the model numbers and it was the correct adapter.
