For your 2018 Jeep Grand Cherokee that doesn't have the factory harness I recommend the Tekonsha T-One Vehicle Wiring Harness # 118727. This custom harness will install by simply plugging into built-in ports behind the driver and passenger side tail lights and then running the hot lead up to the battery. This will provide you with a 4-Way connector to connect with and power a trailer's basic signal lights.

I really like the Tekonsha harnesses in particular because we get far fewer troubleshooting questions with their products than we do with those from other manufacturers. I have attached an installation video for this harness on a 2017 Jeep Grand Cherokee that you can use for reference. The process should be just about identical on your 2018 model.
