When I hook up a utility trailer to my truck(2002 F150- supercrew) the running lights on the trailer work, the signal lights work, but the brake light do not work on the trailer. I have checked the ground and reconnected it and wiring is standard 4-wire hookup. When I have the running lights on and apply the brakes, the running lights shut off. Does anyone have any ideas? Thanks.

does your ford have a seperate turn signal from the brake light. if it does you will need a convertor to add the brake light back into the system to run the brake/turn signal lights on the trailer. also make sure the trailer lights are hooked up right and the bulbs are in correctly, my suggestion, try it on another truck and see if they work correctly. and which ground are you checking the one on the trailer or truck, dont rely on the ball mount to ground correctly

check from furthest point of plug for frayed wires running lights are brown wire and yellow and green wires are turn signal brakes are yellow and green together also use test light on truck plug see if each prong is sending proper signal.
