Wire color used for the tail lights on any given vehicle is not always the same within the same model year of the same vehicle. Based on that you would have to test the wiring with a circuit tester like # 3808 if needed to find the function of the wiring. But it is unnecessary for your vehicle.

You need a wiring harness specifically made for a 2007 Jeep Grand Cherokee. You can use # 118425. It takes all of the guess work out and you will not have to test wiring or splice into the vehicle wiring. I have included a link to the instructions and a link to a video showing a typical installation for you.

If you need to add a 5-Way like # HM37908, then you can add adapter # 20036 after you install the wiring harness. I have included a link to a video showing a typical installation for this adapter.
