Review on Efficiently Control Your Cooling Fan with BECKARNLEY 203-0276 Module by Jason Rodman

I installed this yesterday and it fixed my 370z problem with the radiator fans always on (this behavior is failsafe if the existing control module fails). This is a simple installation and takes 3 minutes. Simply unscrew the old control unit behind the radiator fan, pull off the 3 plugs and plug in the new one. To test this, I drove until the car warmed up. At around 218°F, the new fan control module turned on the fans as expected.
