Hi Jose!
I do have a wiring harness that will fit your 2013 Buick Enclave, but it technically isn't a "T" in shape. That said, what you are looking for is the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C56245.
This is still a plug and play harness with no other wiring needing to be run anywhere, but you will need to install a few fuses and diodes to get it working. The instructions go over where these need to go very well, so there will be no guessing when you get to that part. The port this will plug into is also pretty hidden, so I included an install video we did on a 2014 Enclave. It will definitely help.
Do you already have the hitch? And what are you going to be towing?

Jose I purchased this a few years back. I had a hitch because I use it for my bike rack. I wanted to rent a trailer so needed the wiring. The expert above states it all correctly. But instructions take you through it all pretty good. The one thing I might suggest loosening things at the back panel were somewhat of a challenge so I decided to see if I could fit my hands up there without doing all those steps. Somehow I managed to get it plugged in correctly to the manufacturer plug. It all worked great tested with a meter after I finished before we went to rental place. So look up there with a really bright light until you see what you need to plug into and then try getting to it just squeezing your hands up there. Saved me a bunch of time.
