So my son bought an older boat and trailer and has replaced the wiring. It has the flat 4 no brake set up (Jon boat) . new lights and completed wiring kit. The lights and wiring have the "white" ground wire to the trailer frame. Cleaned off paint and ring terminated each to the frame. Only side marker light work. Ran a jumper wire from one of the light grounds to the truck frame and all works fine. Truck connected to the trailer hitch like normal. So how does one properly ground a trailer???
