Did you guys ever solve the issue with your trailer wiring? I have a 2000 Expedition with only one brake light on three different trailers no other lights work. They were working fine and the work fine on other vehicles. I know it could be anything but I'm not sure if it's a known issue that the plug by the rear wheel back to the adapter gets bad or if there is a typical issue that lies elsewhere. I'm just trying to find where to start????

Same exact problem. 98 Expedition. I've tried 2 seperate trailers so I know it's the truck.
Running lights work. Blinkers and brake lights do not.
Can't find any fuse that refers to this circuit.
Have you checked the plug from your tow bar to fuse. it could be wired wrong.
