Parts Needed to Add 7 Way Connector to 2018 Jeep Grand Cherokee

Question:

I need a 7 pin wiring kit or adapter from 4 pin to 7 pin for a 2018 Jeep Grand Cherokee. When I look it up, only a 4 pin comes up.

We've got just what you're looking for, so never fear; in this case, it's just because there isn't a factory plug and play option for a 7 way available. In order to add a 7 way to your 2018 Jeep Grand Cherokee you'll want to use the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7, which will allow you to use your 4 flat to add a 7 way. This kit comes with all of the parts and wiring you'll need to complete the installation.

If you don't already have a brake controller to control your trailer brakes, the Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional # 90195 is what I recommend. The P3 provides proportional braking for your trailer, meaning that the brakes will be applied with the same pressure as you're pressing on the brakes in your Grand Cherokee. The P3 is one of our best reviewed and most popular choices, and I don't think you can go wrong with it.

I've linked some review and installation videos of these parts for you to check out.
