Your generation of 2002 Jeep Grand Cherokee with a factory 7-way does not have a quick-install brake controller port but I can help guide you through the install process of a brake controller like the Prodigy P2 part # 90885. We had the chance to install this controller on a 2004 Grand Cherokee and used the install kit part # 5506 to wire up the controller to the factory wiring/7-way. If you check out the install video link I attached you'll see the entire process outlined.

The wire color you should be looking for is purple and brown. I attached a picture of where we found it on a 2004 Grand Cherokee that would be same as what you have. Fast forward to the 8:42 mark of the video I attached to this page for more info on that.
