Hello all, I have purchased a folding trailer with electric brakes and have no idea how they work. My boat trailer has four wires on a flat connector and my new RV has six on a round plug. I have and adapter that connects my four plug to the six plug which allows the brake lights, running lights and turn signals to work properly. Does this mean the electric brakes will also be working or do I need a controller? Will I need to do anything else to the wiring for the battery on the trailer to charge as well?Thank you for any help
