This is really difficult, but essentially it slides in - with no discernible click. A *slight* tug on the lever lets you know its connected. Horrible thing.
Use the ‘bic pen’ trick and you don’t have to remove this for most things but I had to go ‘back in’ to remove the super drive. I then used the tip next down and removed this connector at the screen also and put this end back in first with no screen in the way.
The is a great tip
The Bic tip is a great move… many thanks. My third time inside mine now as I try to resolve a random restart issue - fitted OWC sensor on 2nd time in but now I’m putting the old drive back to see if it still occurs.
Going to be under there again - so much easier with the Bics
