I spoke with my contact at Tekonsha regarding your 2018 Jeep JL Wrangler Unlimited. At this time, there is not currently a Plug-In Brake Controller Harness available for this model Jeep. He was not sure if the JL model is even equipped with a factory port that a plug-in harness would connect to. You can check beneath the dash of your Jeep to see if one is present.

Your only option right now will be to simply hardwire a brake controller to your Jeep.

If you do not already have a trailer connector at the rear of the vehicle, you will want to start with this. If there is not a 7-Way OR a 4-Way, I recommend installing the Tekonsha Vehicle Wiring Harness Kit # 119147KIT. This is a universal, hardwire kit that will let you install a 4-Way connector on the Jeep. A circuit tester is included to help with determining the correct wires to tap into on the vehicle.

I have attached the complete installation instructions that you can take a look at.

From there (or if you already have a 4-Way), you will want to install the Universal Wiring Kit # ETBC7. This kit includes everything needed to install a fully functional 7-Way from the existing 4-Way, along with the additional wiring needed to install a brake controller. I have attached a great article that details the installation steps for this kit that you might find helpful.

Then, for the brake controller itself, I highly recommend the Tekonsha Prodigy P3 # 90195. This is a great, proportional controller that will activate the trailer brakes at the same time and with the same intensity that you apply to them in the Jeep. It features an easy-to-read LCD display, storable settings, and continuous diagnostics that will alert you to any potential issues.
