Have a dashboard switch that goes directly goes to the radiator fan control input on the engine. Manual control. Possibly: add an input to the Arduino to see when the fan is on.
Future possibility
Add radiator fan control output back to the Arduino. Output appropriate signals to control the radiator fan, probably dependent on radiator temperature.
