WILL NOT FIT 2021-2024 REVERSE MOTORS WITH PART NUMBER ENDING IN "C" (83388-09C) 
The solenoid will NOT come with a plunger.  You are to use the plunger that comes out of your original motor.  They no longer make the one you need.  The one in the photos is only for reference.  It is not the same and will not work.
