I have this option on my 2020. It comes with a camera, a 20’ trailer harness, and a replacement trailer connector. You can crawl underneath where the spare is and easily disconnect the old trailer plug in 2 minutes. Then pop the one in that was included with the kit. It will basically have the normal round connector on top and a new camera plug on the bottom. The harness included plugs into the bottom plug and runs back to the trailer and plugs into the camera. Easy DIY project. Took me about an hour.
