Remove the larger, clear liner from the inner housing adhesive and put it in place.

Use the cutouts for the small silver pads to help align the adhesive.

Hold the adhesive in place with your fingers and use the flat end of a spudger to firmly push down on each piece of adhesive, securing them in place. The rear cameras can make it tricky to secure the adhesive, so take your time and make sure they're firmly secured.

Slowly remove the colored liner using the pull tab on the top edge.

If the adhesive starts to pull up with the liner, lay it back in place and use your spudger to secure it again.
