Absolutely. If your 2018 Jeep Wrangler JL has the 7-way installed, then you will use Wiring Kit # 5506. If your vehicle doesn't have trailer wiring, then you can use the Universal Brake Controller Wiring Kit # ETBC7. This kit comes with everything you need to connect to a 4-way wiring harness. If you don't have that yet, then I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. This will install behind the tail lights and draw power directly from your battery. When used with the # ETBC7, you will have a 7-way trailer wiring connector and be able to connect a brake controller for electric trailer brakes. I've attached an article and some videos to assist with the installation.

For a brake controller, I recommend the Tekonsha Prodigy P3 # 90195 for the clear display and easy function. The LCD screen gives you information as well as easy to use preset options. If you will be pulling a trailer off-road on Jeep trails, then I recommend using the Redarc Tow-Pro Elite # 331-EBRH-ACCV2 instead. This controller has the ability to switch between a proportional controller for on the road driving and a time-delayed user controlled mode better suited for off-road use.
