This is a harness to prevent the bothersome check engine light and DTC P0073 on Ford Superduty trucks 2017+ after installing mirrors that aren't equipped (small mirrors or tow mirrors). This listing comes with a jumper lead and a temperature sensor along with instructions to install on the passenger side. This harness is compatible with Ford Superduty (F250, F350, F450) trucks 2017+.
Simply slide the pins into the passenger side connector in the correct location and turn the check engine light off! This often also prevents the air conditioning from working, so after you install this and clear the code the AC should resume working.
