Near Intersection of I-35 & I-90 Southern Mn.
I would agree with what I've seen. The ones I've seen have the two terminals isolated from the frame so the polarity is not important. If the PWM valve should happen to only have one terminal then the frame is being used as a connection and then the output from the controller would be important.
