Trailer Hitch Harness

I have a 2012 CT-EXL that I bought in the fall of 2021 (Midnight Blue, Black interior, 107,000 miles). I want to install a trailer hitch on it and I am doing initial research on either doing it myself or getting it done somewhere that installs them. According to the CT shop manual and posts on this forum, a connector for the trailer lights in a 2012 model is located behind the body panel in the rear cargo area on the left (drivers) side. I removed the storage bin on that side, looked up behind the panel and took a picture of what I think is that connector. I am including that picture to get confirmation from someone who has done this before. I did not cut the protective tape off of it yet, till I can take the body panel off to get to it better.
Thanks
