Hi Kirk!

I can definitely help you get your 2025 Jeep Grand Cherokee set up with a 5-Flat! With that being said, there isn't a fully plug and play option for that, so you will need to start with the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C27BR.

This is a plug an play 4-Flat, though one wire does need to be run up to the battery for needed power. From there, you will want to add on the Curt Trailer Connector Adapter - 4-Way Flat to 5-Way Flat - Vehicle End # C57187. This needs to be spliced into your reverse lights (with the included quick splice connector) and then just plugged in the end of the 5-Flat. Little bit of a pain, but just take your time.

Then to mount it, you will want the Curt Mounting Bracket for 5-Way Flat Trailer Connector # C58303. You can either drill this into something, or you can add on the Curt No-Drill Bracket # C83DR. This would go around the hitch and you wouldn't need to do any drilling, which is nice.

What are you going to be towing? Most 5-Flats are on boat trailers, but I have seen them on a few other things as well.
