This listing is for a genuine Mercedes repair harness for the outside air temperature sensor that typically sits in the bumper.  These sometimes pop out and wreck the sensor itself, and also the plug and the cables.  This item will allow you to crimp a new one on and be ready to go in minutes.  These are assembled here at Vaco with genuine Mercedes parts and trained technicians.  Every sensor is tested before shipping.  Free and fast shipping from a Mercedes repair shop that's been working on these vehicles since 1985.  Thanks!
