Brake Controller on 2001 Ford Expedition is Only Working with Manual Override and Not Brake Pedal
Question:
Installed with the adapter and plug in, and the controller activates the trailer brakes when I press the slide but not with the pedal. Any help?

When a brake controller works with the manual override lever but not with the brake pedal that usually indicates a problem along the red wire. In this case, since it is a plug-in harness, it is not likely that the red wire is in the wrong location. But just to be sure the red wire should be in between the black and blue wires on the end that plugs into the vehicle.
The most likely culprit is a blown stop light or CHMSL fuse. Use the owners manual to find the location of the fuses to check them. You will also want to make sure that the controller is mounted within the ranges specified in the instructions and that it is not tilted or turned to the side. Also make sure that the power output is set high enough.
