That specific fan isn't easy to control. It has 8 speeds and is controlled by a 3volt plusewidth signal. 10% PWM = off, 20% = first speed, 30% 2nd speed, ect until 90% =100 % fan speed.


I built this fan into a 124 fan shroud and use my PCS trans controller to provide the PWM signal v/s coolant temp. It works really, really well. The temp needle never uncovers the top of the 8 on the 80C marking.

Buying a PWM standalone fan controller would be worth it to use the 600W fan. The viscous fan clutch setup on these cars is absolute crap.
