Hi Brad!

Does your 2016 Jeep Wrangler have an aftermarket 4-flat already installed? If it does, you can skip to the next step. If it does not have one yet, you will need to start with one and the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55124 is a quick and easy one to get installed.

From there, you will want the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires # ETBC7. This will piggyback off that 4-flat and will get you the rest of the functions needed. The last part you will need is a brake controller.

I am preferrable to the Redarc Tow-Pro Liberty Brake Controller w/ Universal Wiring Harness - Dash Knob - Proportional # RED52VR as it's very reliable and easy to use. It also doesn't take up any of the foot well area, and being 6'5", this is a huge plus for me. I saw you were looking at a Tekonsha controller, but they are having some issues at the moment so I would recommend going a different way for the controller. The Redarc is more expensive, but I really like them.

What kind of trailer will you be towing?
