Hey Tom, if you are wanting a 7-way trailer wiring harness that fits your 2016 GMC Acadia the correct kit would be the part # 118271 or if you need a 4-way part # 118270. Both of these kits install easily and are plug and play like you are wanting. They also come with all of the needed components to activate the factory wiring as well.
Do you need a hitch as well?
