There is 12 volt constant at the plug and the DME sends a signal to control the speed of the fan by varying the pwm signal.
Unlike the previous design of using a relay to provide voltage to the fan and resistors to control the speed of the fan everything is done digitally.
On my 2001 M54 engine X5, the fan fuse is located in the fuse panel behind the glove box.
