Should be on any car that has an external temperature reading. I know my Regal has it with the Dual Climate control that shows the outside temperature. If you have a mirror that's supposed to show the external temperature it would have it also. My GTP doesn't show the external temperature so I'll check when I get home if it has the sensor or plug. Might be like the HUD units where they put all the wiring in most cars even though there's no unit. Does the plug look weathered, connector corroded, or does it look like it was connected to something until recently?Originally Posted by ljmonnin12
