They certainly did, mine not excluded. My wiring harness is brand-new, about two months old. The external temp sensor is not part of that wiring harness, but from what I gather it's a PITA to replace because the cable goes through the engine bay, not sure if it goes all the way back to the instrument cluster. I even read that many techs just cut the cable and splice the new sensor in. If I'm gonna do that then I might as well just replace the thermistor at the tip.
