It goes on the inside of the back of the topscreen cover next to the 2 camera holes. https://d3nevzfk7ii3be.cloudfront.net/ig… Update (09/08/2015) Proof. http://i.imgur.com/DmD1Kje.jpg http://i.imgur.com/G5Nujb7.jpg
That is a micro switch which recognize flip status. when you close the flip screen goes to off mode by that switch.
The LED plastic. it goes into the top left corner below the motherboard, under the left hinge.
