See step 22 to get a clearer picture of what the connector looks like when it is separated from its socket. Your replacement screen will have a new socket (i.e., the bottom piece of the connector). My replacement screen had a new socket attached to the unit by a thin piece of plastic. For reassembly, when working the Home Button/Touch ID assembly back into the new screen, I had to work the connector cable under the socket in order to get the connector re-attached.
Solved it myself. Firm pressure did the trick.
Ok. My screw is stuck. How do I remove it? Philips head is stripped.
At first I didn’t understand why I needed to transfer the screws from the old drive to the new one. Then I figured out that the screws are used as pegs to keep the drive in place.
Also, the software side of things confused me until I found ifixit.com’s video on copying the old drive to the new one. On YouTube it is titled “How to Transfer Your Mac’s Data to a New Hard Drive SSD”.
ifixit.com has some amazing tutorials. Thanks! I can’t believe I’m running the latest OS version on my mid 2012 Macbook Pro!

Yes, buying the kit and components from ifixit made the process so much less complicated. I also replaced my hard drive while I had the computer open. Both hardware replacements were so much easier than dealing with the software part of things.
I used the spudger to gently ease the battery connector out. I then placed a q-tip between the connector and it’s socket to avoid making an accidental connection. A toothpick or some other soft stick might also work.
To keep track of screws, I used the suggestions above by taping a photo of the lower case to a piece of corrugated cardboard and inserting/taping the screws in place. Also, as some have noted, the screws go back in at a slight angle; they are angled toward the center of the unit.
