What year and size is this Brute? My suggestion is to go back the way it came from the factory except one modification,,a switch bypass for those emergency moments. Let it work like it's supposed to in the mean time. Besides, the fans weren't built to be continuous duty motors. They will toast running all the time and then what will you do out on the trail when that happens.

From 2008 on they stopped using a fan switch on the radiator and went to a relay triggered by the ECU which gets it's temp info from the temp sensor. That relay's "line" power comes from the same auto breaker-type system it had prior to 2008. So...below is the fan control system for yours and what you have to do to tie-in a bypass switch. Returning your system back to factory may be the toughest part...but really it's all basic stuff once you look at it.

Thanks for the info. I wouldn't have thought to bypass the relay. Unfortunately to get back to factory I have to buy the relay. Everything else isn't that hard. I never throw anything away so I have the stock fan connector ect.From 2008 on they stopped using a fan switch on the radiator and went to a relay triggered by the ECU which gets it's temp info from the temp sensor.

They are not the same. I can give you a manual for yours and it does have the full wiring diagram in it. The link is below. It will only be good for 48 hours. After that it will no longer work so download it soon.
