Hello everyone , I am planning on using a set of spal radiator fans on a Subaru Impreza GC8 . The oem fans have 3 wires while the spal have 2 . From a little research I found that one wire is low and the other is high speed . Of course the 3rd is ground . If this is actually true what would be the best possible way to wire them at least temporary as in January will be installing a standalone and I think it would be possible to pwm them .


Hello i would recmmend wiring then to high speed to be safe

Hello Ross , thank you for your reply . I wired it to the high speed only and works really well . Thank you.
