My 2010 F150 did not work either until I plugged in the fuse and relay. I guess you got them plugged into the correct position. I found my fuse and relay in the glove box in an unmarked envelope with no instructions what they were for haha.. Finally read something in the manual about needing the fuse and relay. This also means you have to have the ignition key turned on as well when using the brake controller.
Mine worked just fine after putting in the fuse and relay but I also discovered another feature I don't like that being using the pedal brakes doesn't engage the trailer electric brakes when you speed is less that 10MPH or so. I have to use the slider lever if I want to hold the trailer brakes on at a stop sign on an incline. I also think all of those connections have an internal fuse in the truck fuse panel for the trailer lights as well. Check the manual
Everything is disconnected on mine when my ignition key is OFF after it times out. I kinda wish I still had my P2 controller haha..
