For your 2019 Jeep Wrangler Unlimited JL Rubicon to use the Roadmaster Even Brake Portable Supplemental Braking System - Proportional # RM-9400 you will need the 12 Volt Outlet Kit- 20 amps # RM-9332 to get the power needed for the system. I do recommend using the Roadmaster Battery Charge Line Kit for Towed Vehicles # RM-156-25 to get the battery charging needed so you don't deplete your vehicle battery on long trips.
For your vehicle tow bar wiring to your LED lighting system I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This system will give you diodes to splice into your factory wiring to give you a very clean look utilizing your factory LED tail lights and still protecting your system electronics from feedback or overload.
If you have questions about any other products and compatibility let me know.
