I would take my multimeter to it but there's no good access to the leads because of the environmental seals - can you simply tell me which colors are what? Or simply which lead provides the variable voltage from the thermistor? Also what's the most convenient source of +12v (ignition on) to tell the fan controller when the ignition/engine's on and off - my guess is that one of the leads going into the IAT is +12V? - TIA - john.
here's the image from my engine:
