Just purchased a dual headrest dvd system that is not going to be integrated into anything else in my 2001 RX 300. I just need the two headrest DVD players to be powered and cabled between each other. Does anyone directions on gettings the wiring down through the seat? I can handle doing all of the other routing through the vehicle for power, etc... I just don't know the easiest way to get it from the headrest to the bottom of the seat. It looks like the panel on the back of the seat will come off, but I don't want to start pulling on it and possibly break any clips or hooks that could be holding it. Any information would be great. Thanks.
