Hi Willis, Great question!

For your 2021 Jeep Wrangler Unlimited, the plug and play flat tow wiring harness you will want is the Curt Wiring Harness part # C96JR. It is designed specifically for the Wrangler and plugs into the factory taillight wiring so your motorhome can control the Jeep's brake lights, turn signals, and running lights while flat towing. We currently do not carry a Blue Ox option.

If you are building a complete flat tow setup, you would typically pair the wiring harness with a base plate, tow bar, safety cables, braking system, and a 6 way or 7 way electrical adapter depending on your motorhome setup. The C96JR is one of the nicer options because it is a custom fit harness and avoids the more involved diode style wiring installations many older flat tow systems required.

Just to make sure I point you toward the correct remaining parts, do you already have base plate and tow bar installed on the Jeep, or are you starting completely from scratch with the flat tow setup? What wiring connector do you have on the motorhome?

I installed in my 2026 wagoneer along with an interior cigarette lighter socket along with the Blue Ix Baseplate and the BlueOx Patriot III brake system. Worked great. Just towed the car 3,000 miles after two 300 mile trips with no issues

@LawrenceR That is great to hear, and thank you for sharing your experience. Now you've got me curious, where did those 3,000 miles take you? Any favorite stops along the way? It's always fun hearing about the adventures that these towing setups help make possible.
