While carefully lifting the keyboard ribbon cable with one hand, use the tip of a spudger or your fingernail to flip up the retaining flap on the keyboard ribbon cable ZIF socket.
Be sure you are prying up on the hinged retaining flap, not the socket itself.
Pull the keyboard ribbon cable straight out of its socket toward the front edge of the Air.
Remove the 1.4 mm T5 Torx set screw from its tapped hole near the front edge of the upper case.
During reassembly, do not over-tighten the set screw, as the button will cease to click at a certain point. Adjust the set screw until the movable side of the trackpad has minimal play.
Use the flat edge of a spudger to carefully lift the edge of the trackpad closest to the keyboard from its recess in the upper case by lifting it away from the brackets attached to the upper case.
The screws are not Philips 00. They are smaller than Philips 000. I am looking for a screwdriver in that size.
I have the iFixit toolkit, and the PH000 tip simply did not fit into the head. The J000 tip could remove a couple screws, but started to strip the head of two others before I stopped. The tip almost stripped the two I removed on reinsertion.
The replacement trackpad comes with a set of these screws.
