2008 Ford F-350 diesel. Has two fuse boxes. One under hood and one inside in passenger kick panel. I have no running lights on trailer. All other lights work fine. I think I had a unplugged harness touch the frame and pop a fuse. But I’m just not seeing any bad fuses. Does anyone know exactly which fuse controls the lights when a trailer is hooked up on that particular vehicle? Some of the fuses are hard to access. Thanks
