The Trailer Wiring 7-Way Upgrade Kit w/ Junction Box and RV Style Connector # HS381-9000 you were looking at will work perfectly on your utility trailer even though it only has 6 wires.

First things first I recommend verifying that the issue is on the trailer side of things and not trucks connector. You can test this by having a friend turn on the turn signals and apply the brakes while you text the pins of the connector using a circuit tester like # PTW2993.

If you have power, then replacing your current connector with the # HS381-9000 and checking the wiring will fix your issue.

If you do not have power, then I recommend checking the towing fuses in the engine bay fuse compartment of your 2016 GMC Sierra 2500 and make sure they are not blown or missing.
