I just installed a Flex-a-lite Black Magic on my YJ which is their universal electric fan kit with built in adjustable thermostat, AC relay, and manual overide. This set me back about $150 on ebay and I checked the Flex-a-lite Website specs on the 475 to make sure on the size and model had what I needed. It was easy to wire, 1 long fused red wire to the battery, 1 short ground wire, 1 control wire. I found it much easier to drain and pull the radiator so I could drill four mounting holes to match up the brackets were the factory shroud mounted and I was done in about 2 hours! Summit Racing also has good prices on them. The 475 direct replacement custom fit for the wrangler but the Universals work well too. They also now sell a 485 Wrangler Extreme but they are about $300 and use S shaped blades for lower noise. The amp draw on the unit I used is 13 amps, and 2800 CFM which is alot of Air flow compared to the stock fan. The fan barely ever runs unless I am stopped at a light for a minute or two. My Optima 800 battery helps too!
