Have a 2020 Reflection 315. The electric brakes are not working. Have had both plugs replaced, trailer and truck. Ford dealer has replaced the brake controller. Did not help. Dealer then connected a different truck to the trailer and still nothing. Both trucks show a "trailer wire fault". All other lights on the trailer work. Turn, brake and lights. The only thing not working are the trailer brakes. In reviewing the wiring diagram, it shows a 400a in line fuse. Does anyone know where the fuse is located? Any other suggestion would be very helpful. Thanks
