These are pulled for fully working Wii consoles. 
These are from the Type #1 Wii Drives found on most RVL-001 shown in photo 6.
These have a few board types inside as pictured in photo 3.
I pull and ship at random for fully working drives. 
This is NOT for the Wii Drive Type #2 found on the RVL-101. 
 This is the Replacement Top Cover and Disk Pull in Sensor & Cable w/Screws ONLY as pictured.
The Top Cover is for any pull in Mechanics issue.  
The ONLY purpose for this is a sensor that tell the pull in motor to turn on when disk inserted. 
This will ONLY fix an issue if your disk does NOT go in at all. 
It will NOT fix any other Wii Drive issues. 
The Wii Drives can have Ton's of Potential Problems.
The last photo shows if this is NOT on then the disk does NOT go in.
No Disk Drive or any other part included but for photo reference ONLY.   
 I have a few of these as pictured.
