MK4 Golf PWM Fan Controller

Dead slow speed resistors on your MK4 Golf?  This PWM fan controller is the cleaner alternative to the traditional 'resistor mod' method.

Integrates using OEM plugs into the original fan harness, this module re-creates a slow speed fan using the high speed side.  The speed is adjustable with the built-in potentiometer.

These can also be used for the aftermarket scene by removing a jumper.  This allows the module to operate in a standalone mode, where the two remote wires will command slow and high speed fans.  Perfect for aftermarket ECUs that can control fan speed or users wishing to have a remote switch in the dash.
