Ok I hate when I don't know something.
I believe to use the E46 PWM module for the front AUX fan:
X60004 to MSS54/HP
Pin 4: Signal to PWM module
Pin 38: Ground from lower rad temp sensor
Pin 39: Signal from lower rad temp sensor
PWM Module:
3 Wire side Blue/Red/Black
Blue: Signal from X6004 Pin 4
Red: +12V (not sure if switched....but most likely yes as I don't think it has the ability to run after power off as the DME is switched power) (12 guage wire or larger)
Black: Ground
2 Wire Side Black/RED
Black to fan
Red to fan
Garry's CAN Box:
Pin 2: AC Pressure Sensor Pin 3
Pin 1: AC Pressure Sensor Pin 2
Pin 6: Ground and to AC Pressure Sensor Pin 1
Since your using the PWM fan (WOOT!) you can control the duty cycle in regards to temp with:
And how that duty cycle is applied at speed:
Meaning at 120km/h whatever temp you are at, the duty cycle will be halved (E46M3). Above 140km/h the fan will be off no matter the temp.
