The fans are under the control of that EZK IGN module., which has two outputs, one for each fan speed. The fan relay is in reality two relays in one box, the module provides a ground to each, as you guessed.

IGN pins 17 and 26 to fan relay pins 1a and 1b

Input to the EZK pins 25 and 27 from the Aircon might keep the fan on too.

Ultimate input to the IGN module must be from the Engine Temp Sensor, but my circuit diagram is missing that section.
