Recommended 4-Way Wiring Harness for 2021 Jeep Grand Cherokee Without Factory Tow Package

Question:

I want to add a 4-way connection to my 2021 Jeep Grand Cherokee. I do not have the tow package but I do have a hitch I installed. What wiring harness do I need and how easy is the installation? Do you have any guides on how to install this if I want to do it myself?

For a 4-way on your 2021 Jeep Grand Cherokee I recommend the Tekonsha T-One Vehicle Wiring Harness # 118727. The installation of this wiring harness is fairly simple, no cutting or splicing of wires is required. The T-One connector plugs into your vehicle's wiring harness behind the tail lights. Once this is done, you will run the hot lead to your car battery, connect the lead to the fuse holder, and the fuse holder to the positive terminal.

I have attached the written instructions, as well as an installation video on a 2020 Jeep Grand Cherokee for your reference.
