iPhone 5 iPhone 5 Proximity Sensor and Flex cable doubt

Hi, a few days ago my phone start to have problem with the light of the screen, my screen darkened and I can barely see my icons or any other think, I left the pone with an unknown "technical" guy and he messed up, now the phone is dead completely, when I plug the battery makes a beep sound, I went with and expert and say the problem was this part i show in the next picture:

I search and someone said to me that the piece I need is the Front Face Camera Light Sensor Proximity Cable Repalcemet, but I bought this piece and I dont see that part of the missing piece, this is how the phone should look with the piece

This is the part I bought http://www.ebay.com/itm/261445487146

The question is, do u think the part from ebay will fit in my iPhone from the first picture? or the piece I need is other one
