Mopar assist could help you. What I do with queries for some parts is email https://www.moparonlineparts.com/ with photos just so they know what I'm talking about. Found them on google and been buying parts from them since 2 months ago.
My friends suggested to get a mopar harness https://www.jeepsareus.com/sku/82215382ab.html. It is my first time to use Jeep for towing as I've been using Ford. Would love to hear if mopar could be reliable in terms of towing.
