Can I put OEM dvd player in my car?

I recently bought a 2012 ford expedition el limited and when deciding I went with this because they came down in price to move it quick. It has all the bells and whistles except the head rest DVD players. But it does have the touch screen system in the front though. I found a totaled 2012 expedition at a junk yard that has these 2 head rest screens for 100$, can I just remove the head rests, or the seats themselves, and put them in? Or is it not plug and play?

I would imagine under the seat are wires to plug in. I've seen lots of unused wiring in cars that didn't have all the options. They don't make separate wiring harnesses for all the different trim levels of one model. It's cheaper for them to make one harness. Move the seat all way forward and see if here are wires under a slit in the carpet. You could look at the one in the salvage yard too. You may have to buy the whole seat. I don't know if all the seats have dvd wires in them, probably not. It's only 4 bolts that hold it in.
