yes simple to do other than you need to have the fan running at a very low speed via a resistor, and kick in when another sensor says the engine is getting a little hot, when I first fitted mine I omitted the resistor so found that even in cool times the fan would kick in with a loud roar for a couple of mins every so often, found it better to have a small air flow constantly (which is what a viscous fan does anyway) and now the full fan almost never comes on, bye the way with no fan at all you run the risk of overheating if stuck in heavy traffic for a long time, Rick
