2007 chrysler pacifica, 2 lcd headrest

Greetings,

This is my first post here so please be gentle.

I have a 2007 Chrysler Pacifia Touring (AWD)  I have the premium sound system. (infinity) with the 6 Disc DVD changer (MP3) and it has a Single DVD (MP3) player.  I also have the flip down roof mounted LCD Screen with the Koss IR headphones.  My problem is I want to add 2 aftermarket lcd headrests screens.  I purchased (2)  7" LCD replacement headrests.  My problem is I can't figure out how to wire them to the system.  I took the interior trim off and looked behind the unit and it does not look like there are standard RCA plugs to set up the video.  (Please note that my LCD screens do not have audio so they will play from the car's audio system)  Can anyone point me in the correct direction.. Can someone please post the complete wireing diagram for the dvd player so I can install the 7" LCD screens.  I really appreciate the help.  Thank you in advance and I hope I provided enough detailed info to get my questions answered.    I went to the dealer and was given a quote of $900 bucks to install the headrest screens. I know this is overkill for pricing.  I  have installed many car stereos and a few dvd systems in cars but this one seems to be giving me trouble. 

Maybe this will help.

You may also want to try ebay to find any adapters that you may need.  Your first mistake was asking the dealership. They overcharge for everything. Good luck with the install. I just finished installing mine and a flip down as well. Do those monitor have ir transmitters for wireless headphones?
