Hey Kelly, in order to have wiring for when your 2021 Jeep Wrangler is being flat towed and also when towing a trailer you would need to install two separate kits as unfortunately either of those can't be used as the other "in reverse".

So for flat tow wiring we have the easy to install Curt kit part # C96JR which plugs right into the taillight wiring connectors of the Wrangler.

Then for trailer wiring you'd want to install the Tekonsha part # 118786 at same time as the Curt kit. These will basically plug into each other and will both work great together.

Hey Kelly, did the Curt and Tekonsha wiring kits work well for your Jeep Wrangler? I'm asking because your experience could help others looking to set up their vehicles for flat towing and trailer towing.
