    If this was available when I was building the Cougar, this is what I would choose.

    What sort of input signals does that fan controller need? A PWM signal or just a temp sender?

    Thanks,

    They are a PWM controller, designed for EFI applications where the ECU controls the fan speed.

    Otherwise just use a temp switch to power a relay when the fans are needed (IE no speed control, just on or off).

    Thanks but what I am asking is if the PWM controller is stand alone with only needing a temp sender or does it need a PWM signal?

    As was said above. It's literally the same controller at the C6 Corvette controller. So it needs a PWM- signal.

    You ever have one of those, "crap, I didn't even think about that!" moments?

    What's the difference between - and + PWM signals? Asking for a friend with a Spal fan and a Holley Dominator.

    PWM- pulses to ground. PWM+ pulses to positive.

    Thought it was more complicated than that.......

    What happens if you send it - and it wants +? System in question is functioning, can't remember what I set it to, do not have laptop to look.

    The magic pixies get out....;-)

    It's hard to set the wrong config because on the pin map you can't configure the same pin as PWM- or PMW+. That's a hardware limitation.
