Use your fingers to flip the trackpad cable towards the bottom of your laptop, so you can access the ZIF connector on the trackpad.

During reassembly:

Don't secure the trackpad cable with adhesive yet—wait until you've reconnected the other end. Otherwise, the cable may not reach its socket if positioned incorrectly.

If you're using the original trackpad cable, the adhesive should be sticky enough to reuse.

If you have a replacement trackpad cable with adhesive pre-installed, remove the liner.

If your replacement cable doesn't have adhesive pre-installed, or if the adhesive isn't sticky enough, apply a strip of thin, double-sided tape to the bend on the right side of the cable.
