Bought a 2014 Rubicon JKU 6 weeks ago. Used Cool Tech harness and was very impressed with ease of installation and quality of the harness. Would buy again.

Used Blueox base plate, easy to install yourself. Took about an hour with common hand tools.
Bought it on Amazon for $358.00 free shipping.
Enjoy!
