I was thinking the same, there would be a light. But finally checked my GTP and the same plug is not plugged into anything and the connectors are corroded. The temp sensor on the Regal is located at the front right on a piece between the AC Condenser and the bumper. It has the same style connector and the same color wires so I think you're good.
