RE: Do 2002 Grand Caravan Sport models have wiring for DVD?
The wiring is not there for the overhead DVD. The 03 unit will work in the 02, you will need the bracket that the DVD mounts to on the roof side of the headliner (it may or may not be there already). Also you will need the cable that runs BTW the DVD player and the factory radio (This has to have CD changer controls on it). I have the wiring harness that runs up the drivers A pillar to the DVD screen if you are interested, PM me.
