PWM for fans, will this work?
I am wanting to power and control my two Spal fans from my Holley HP ECU via a PWM controller (the Ford Fusion version) and have come up with a plan. I know this has been discussed at length in another post bout I would like to get some opinions as to whether or not this will work. Pictured below is a schematic I have hand drawn and a photo of what I have set up in the input/output of the ECU.
