I am trying to install the factory OEM dual dvd headrests (Invision Revolution LT). When I bought the 14 Expedition it was removed. This supposedly was factory installed original to Exp. So I'm trying to install them back in. I have the headrests in, the control box and they are connected. Here is where I run into my problem. I have this plug, I assume it's the power plug. Seems like it's a plug n play for 12V, however after removing the back of the center console there is no where to plug it into. I looked under the passenger seat (pic below) and there is no connection there either. I looked in the fuse panel and no female adapter for this. Has anyone seem this plug and where does it go? I am starting to think the dealership removed a part or something is missing. Anyone that can help will be much appreciated.
THIS PLUG GOES WHERE?

CORD UNDER PASSENGER SEAT
BACK OF CENTER CONSOLE
