Derale Adjustable High Amperage Fan Controller Kit P/N 16778

As always the part arrived quick and hassle free. The instructions are well laid out and the supplied 10 feet of 10AWG is more than enough to route the power wire, a 25 amp thermal breaker is included along with most everything you need to perform the task at hand. Unit controls the fan within a 10 degree window and does run after engine shut down for 1 minute. at half the price of other brands I don't see and real difference other than cost.
