If you are using the 4 wire like the # 16-4B-1 The functions would be as follows:

White Wire = Ground
Green Wire = Right Turn/Brake
Brown Wire = Running Lights
Yellow Wire = Left Turn/Brake

On your camper side I would assume the brown and green would be the same function as the 4 wire. That being said, wire color is not universal. You would need to go in with a wire probe like # PTW2993 to determine wire function for the wires on your pop up camper
