The GMPP harness and ECU in my GTO were purchased in 2008. I don't have a speed input to the ECU. My fans turn on around 210 and turn off around 205.

A buddy of mine assures me he has the PWM fan working on the GMPP controller kit. He says the PWM signal terminal is connector J3, pin 49. Check that you are using that for the signal & not the exiting fan wire that triggers the relay for on/off fan.
