Hey Jimmy, we can certainly help with installing a tow package that includes a hitch and a 4-way/7-way on your 2015 Jeep Grand Cherokee. Lets start with a hitch. For that I would recommend the Draw Tite part # 75699 as it's mostly hidden and it has a mounting bracket for trailer wiring built into it.

Then for wiring you would need to start with a 4-way which we have with the Curt # C62VR. This plugs inline with the taillight connectors of your vehicle and is as close to plug and play as available for your vehicle. To convert it then to a 7-way what you would want is the part # 37185 for if you don't have trailer brakes or the # ETBC7 for if you do with a brake controller like the P3 part # 90195. Not every trailer with a 7-way has brakes though so you should check to determine what route to go with. Let me know either way and I'll make sure we get everything.

@Jimmy Awesome, that means she has the USCAR type harness already and a standard 7-way like the part # C42JR which will plug right into it and also give you a 4-way connector.

@JamesonC Hey Jameson, would it be 57 6 72? Because I have to wire in for a rate controller, it's just a wire with a plug in where I would have to plug in that item number into that and I guess run wires back to the engine compartment and The brake controller please and thank you

@James the Curt # C57672 would be what you'd want if you had a 4-way currently and wanted to convert it to a 7-way and then wire in a brake controller. Is that for sure what you have or do you have something different?
