I have a new one sitting in a box out in the garage. While it is plug in play, it has no diodes, and I am not a fan of back feeding a CAANBus electrical system, hence the recommendation on their website that you disconnect the battery.
I paid a few bucks more and went with the MOPAR Factory Harness. Mine is still under warranty and the dealer here looks for ways to deny warranty coverage, and I don't want to give them a reason. While CoolTech will tell you about the Magnum Moss Warranty Act, they won't pay for the Attorney to battle the manufacturer.
