GMPP LS3 controller with PWM cooling fan?

[samckitt]

Who has successfully done this? I have heard it CAN be done, and heard it CAN'T be done....????

I am using a C6 Corvette fan module.
I have heard the PWM signal is pin 64 on the J3 connector, and have heard it is pin 49. Which is it?

I thought I had it working, but car has been sitting for a while, I have it on in my tune, but when I try to activate it from the scanner tool, nothing happens.

Help

Thanks
