By U.S.federal law you can't drive and have a movie playing at the same time, that wire when connected will only let you watch the movies while the vehicle is in park. To go around this all you have to do is ground the wire, I always just ground them the the radio itself on the backside around a bolt on the radio heat sink, and there you go you now can drive and watch Movies.
