Product review (4 stars): OEM Part
This is an OEM factory part for refrigerators made my Whirlpool. The butt splices to attach the thermistor are included,  To locate the thermistor on your refrigerator, look up the exploded parts diagram for you model.  In my case it was located under the interior light cover.  There are YouTube videos describing how to install the part.

I would have given it five stars if Whirlpool had designed in a detachable connector rather than requiring you to cut wires and splice on a new piece,  Other than that, it replaced the old part perfectly and my refrigerator is no longer freezing vegetables,
