I just registered after reading this entire thread.
I'm trying to figure out how to wire up a SPAL brushless fan using the factory C6 PWM controller.
Essentially I just want to replace the OEM fan with a more efficient brushless fan and use the PWM controller and ECU to control it.
The new fan has a PWM controller input, but I'm not sure if I can wire it directly to the PWM wire on the fan controller.
