This innovative Fan Controller can operate two fans at different temperatures or a single two speed fan at different temperatures. Adjustable operating range of approximately 140 degrees to 230 degrees with our exclusive lug sensor that mounts under almost any engine bolt. Creatively reduces surges on your alternator and engine. Works with or without A/C request. All Ron Francis Fan Wiring Kits come complete with heavy gauge crosslinked wire heavy enough to carry the load of these fans.
