    Welcome to the club. I would call fan compaines like BeCool and Flex-a-Lite and get there recommendation. They have conversion kits for alot of truck. Also tuners like BlackBear, PCM4Less and NelsonPerformance have electronics to run the fans of the trucks computer rather than off a temperature probe hooked to the radiator or radiator hose.
