I have a 2011 jk and set it up for flat towing using the following:
- Roadmaster xl brackets $300 Hitchsource.com
- Wiring harness $100 cooltech.com
- Roadmaster Brake Relay kit $28 etrailer.com
I already had a Roadmaster Falcon Towbar and a Brake Buddy. I also added a rear hitch Rugged Ridge (factory wiring included) from the jeepwharehouse.com $89 so that I could put a bike rack on the rear.
Install took some time and patience but not too bad. Made for a great winter project in the garage.
Hope this helps for those looking to do the same.
