For me the angle of this picture was kind of confusing. Just to make sure it is clear, to anyone else (and they don’t break off the protective plastic piece for the pins like I did), the hinged flap is at the opposite end from the ribbon cable. Where the spudger is in the second picture kind of looks like the middle of the part, but no. From the angle these pictures are taken, it is the plastic piece closest to you. I don’t know why it took me so long to figure this out, and I feel like a bit of an idiot for not doing so more quickly. But hey, maybe reading this comment will help someone not make the mistake I did.
