had a little trouble with theses screws. they were just barely too deep for my 54pies bit driver kit to reach. I ended up inserting a small wad of paper into the shaft of my driver so the tri-wing bit stuck out far enough to engage the screw. (I used the tweezers to remove the paper when I was done) :)
surprisingly, this was the trickiest step for me. I almost completely mangled the wires when my tweezers slipped as I was attempting to remove the connector.
