Ipad Air 2 Sleep / Wake Sensor transfer

Hi all, Recently i have come come across an iPad air 2 A1566 which i replaced the screen on. I also noticed it has a small sleep wake sensor at the bottom of the iPad to the left of the home button. This requires transferring from one screen to another and also involves soldering. I have tried to do this following a very vague guide on here which includes a video but to no avail. Could someone please provide a link or some step by step detailed instruction on how to do this correctly.

Thank you in advance.
