"Wiring fault on trailer"
Anyone run across this? I have a 2010 F-150 with an integrated brake control. A "Wiring fault on trailer" alert popped up on my dash, with an annoying chime. I haven't had a trailer on in a while, this just came up out of the blue. 4 pin and 7 pin connectors look good, I always use dielectric grease. I has been rainy here lately. Anyone have any thought?
