I have a Gen 2 V6 fan assembly I'm swapping over to my Gen 1 V8. The fan has the large and small connectors. I saw an older thread showing a fancy controller. I just want the fan to kick on high at a certain temp, say 185, and shut off at another. I understand the larger connector wires are constant power and ground and the 2nd smaller connector has a "power on" wire & "signal" wire. Can this power on wire be used with any cheap aftermarket temp controller to kick the fan on and off at full speed like a manual toggle switch ? I assume the signal wire is to control rpm and if ignored the fan defaults to full speed ?
