The Tekonsha Prodigy P3 Trailer Brake Controller, Item # 90195, does not come with the harness because each harness fits a particular vehicle. For your 2018 Jeep Grand Cherokee, you need the Tekonsha Plug-In Wiring Adapter, Item # TK93VR, if you have the factory 7-Way connector. One end of the harness will plug into the Prodigy P3 and the other end will connect directly to the built-in port beneath your Jeep's dash.

I have attached an installation video on a 2014 Jeep Grand Cherokee to assist you. The installation on your 2018 Jeep Grand Cherokee will be similar.

I have also attached additional articles for you to check out.
