Hey guys I've got a Q. My father in law just bought a used 2012 f150. I know it's not one of our trucks but I'm hoping y'all can help me figure out something. While we were taking the shell off the bed we noticed that the previous owner had installed some led lights under the bed rails. There is a switch connected to the wiring and this all connected to some leds in the topper. Problem is we can't seem to get any to turn on. The switch does nothing and the button on the led on the topper wouldn't work either with the switch in either position. Any ideas on how to get them to work?
