Broken Screen, can I use the iPhone 6 Plus display to repair?

No, and according to unconfirmed sources, iPhone 6s displays are not replaceable altogether, likely because of 3D Touch calibration issues.

"I feel that they're overselling this 3D Touch. It's just force touch, be realistic Apple.

Alright, prasadjalal. Doing things as cheaply as possible, usually ends poorly. At the very least, it'll work for a short period, and then you have new problems. I understand it's frustrating, after you just spent money on your new phone. But, you'll probably want to spend the money on a quality product"

I just ordered the wrong part for my sisters 6s plus, the ordinary 6 plus screen connectors are different and largely due to the fancy home button also the camera won't stay in its spot. So if it's a 6s plus get the correct screen

I have an I phone 6, digitizer has 3 plugs which phone is it? I ordered the digitizer supposedly for the one I have A 1688 but got the digitizer with the 4 plugs. Which one do I need?

No, because the technologies in both phones aren't the same

Thank you for the quick response but I am still lost. Yes the digitizer that was shipped out to me has 4 plugs and it has it all, speaker, camera, etc. Even if I took that off and transfer the old parts, the remaining plugs do not match the sockets on the board. :( ):
