To control your 2020 Jeep Wrangler's lighting you will need the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267. It sounds like you may already have the cable, if you do you will just need the following parts to connect to your Jeep's lights and control them:

Roadmaster Universal Hy-Power Diode Wiring Kit item # RM-152

RoadMaster 6-Wire Trailer Connector - item # RM-910030-7

Roadmaster Bent Electrical Socket Bracket item # RM-910030-5

The rest of the parts you will need to flat tow your 2020 Jeep Wrangler are listed below:

Tow Bar and Safety Chains - Roadmaster Falcon 2 Tow Bar item # RM-520 and item # RM-643

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM-521453-5

Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes. You will also need the Roadmaster Stop Light Switch Kit item # RM-751490 to ensure that your supplemental braking system is properly positioned and working effectively. This kit activates your RV's monitoring system to alert you when the brakes of your towed car are being applied.

High Low Adapter - The tow bar needs to be within 3" of level. If you measure the height of the inside top of the hitch receiver tube on your RV, and the height difference is more than 3 inches above/below the base plate tab height, you'll need a high/low adapter. I have linked a FAQ article that explains all this in more detail along with our selection of adapters.

I have linked several installation videos below along with the written instructions to help you get these parts set up. The recommended wiring will not be effected by the Curt wiring harness you have already installed. There are no plug and play options to install a 6 pin connector so you will have to splice some wires.
