We bought this vehicle and our tent trailer has a 7 round prong plug, and our acadia only has a 4 prong plug, is it possible to put in electric brakes and a wire harness with a 7 prong plug to be compatible for our tent trailer which has electric brakes, and 7 prong plug.

I would suggest you talk to your RV dealer. I'm sure they have addressed this problem many times.

My 07 came with a 7 pin plug - I had to buy a 4 pin adapter for towing smaller trailers. The hitch was dealer installed as part of the sale but supposedly was the same hitch as would have been factory installed.
