Compatible with Dodge Ram 3.0 L Diesel engines (2014 and newer) OEM Block Heaters for Ram 1500 chassis. 5 foot long power cord for 120V AC Made with a high quality flexible rubber sheathing (not a cheap plastic covering that cracks in the cold) This little cord can be a hard to find part ..... and worth every penny in a cold climate.
