[DeTomaso] indicator light

[Tomas Gunnarsson]

Since the sender grounds the relay coil when the fan comes on using the relay input as awarning light source will be an indicator for when the fan is _not_ running. Unless your fan power source is unfused I see no increase in fire hazard from using the fan output to indicate fan operation.
