Use the T6 to adjust the Trackpad sensitivity screw: The screw adjusts the 'travel' of the trackpad button and the force needed to register a click successfully. Turning the screw clockwise reduces the required travel, and dampens the sound of the click itself. But be very careful not to turn it too tight. Turning the screw counterclockwise increases the travel, and makes the click louder.
I used two small flat head screw drivers, one on each side to pry out the connector. This created less pressure from me and reduced my chance of cutting the wires.
The screwdriver provided in the kit by ifixit is a magnetized screwdriver and works perfectly!
