There are a couple of different options for fans on those ECU's.  There are two wires that can be Fan Relay or Fan speed.  When looking into the ECU's main connector they are third from top left and third from bottom left (above and below each other).  Depending on what combination of fan relays and speed controllers are fitted to your engine will depend how the fan needs to be controlled.  Aux 9 is connected to the top row pin and Aux 13 is connected to the bottom row pin...
