I am looking for some help with an unidentified wire coming out near my thermostat. There is a wire that plugs into the thermostat which is brown and then there is one that is brown/blue that is not plugged into anything. On the back side of the engine, there is a brown/blue wire plugged in near the bottom of the oil reserve bottle. Any idea where the loose brown/blue wire coming out near the thermostat needs to be plugged in? Its a 90 degree fitting.
