Hey Chris, actually my fan turned out to be a 15" Flex-a-lite Black Magic 150 Universal which comes with shroud, adjustable thermostat and sensor, AC relay, manual overide, wires, fuses, mounting brackets and great instructions, easy install! It is very a strong heavy duty design and will handle whatever you can throw at it. I have seen some cheap e-fan conversions which had no shrouds cause overheating. Stay away from mounting through the radiator types, off-road bouncing will lead to a damaged radiator core. The S blades make less noise but cost more. I live in the desert and wanted the best E-Fan I could buy, my local speed shop also sells them for about $199 but ebay stores may save you some $$.. My YJ install was really easy, on the TJ you will need to re-mount the overflow tank and power steering resevoir, I plan on doing the same mod to my TJ this summer, Flex-a-lite system is well worth the money and made in USA! Dont take chances with a system as important as cooling.
