Both the Tow Ready Wiring Harness part # 118449 and Curt Harness part # C56217 that you referenced have been confirmed to fit your 2015 Toyota Highlander and would work well for you. But we tend to have more luck with the Tow Ready harnesses. They tend to last a bit longer than the Curts so I would recommend the # 118449 for you.
I attached an install video for you to check out as well.
