Took me 2.5 hours to complete this. Had a hard time getting the factory cable connector off the power button. Used some 3M Double Sided Adhesive tape- 2mm width, Black color to hold the new replacement cable connector in place on the power button. An IFIXIT video showing how to install the connector onto the power switch would be a big help. Had to use a You-Tube video to complete that step. Also, a good reminder to ensure all your connector cables are clear when reinstalling the logic board. You definitely don't want to pinch any of them. Follow the directions carefully and patience is a must! Wasn't that hard for my first time replacing this flex cable.

Definitely was a very small snug fitting connector.

Thoroughly read the directions prior to installation to ensure how to install the adhesive strips properly. Was able to remove the old battery adhesive with very little problems. Just took my time and removed it by pulling it out slowly. If you follow the directions you shouldn't have a problem. Took 7 minutes to remove the old battery and install the new one.
