It sounds like you are just needing the Hopkins Adapter 4-Pole to 7-Pole and 4-Pole # 37185. This will plug right into the 4-Way flat on your tow vehicle and provide a 7-Way to connect with your trailer. Since you are only needing to power the lights on the trailer, the additional wires can simply be tied off as they will not be needed.

I have attached a short video demonstration on this product that you can also check out.
