Installing factory DVD

[Ratchetman]

Hello all, I recently fixed up a 2004 for my family. My question is about installing a factory DVD player in a van that didn't come with one. I have access to a wreck at work that has a working DVD in it and I have removed most of the parts. I was wondering, does anyone know if I need to pull the dash and the rest of the interior to remove the whole harness? Do I need the whole sound system too? Or did these vans come with the wiring for the DVD player?

Good luck on this project it sounds complex, I believe you need the radio also and the harness associated with the dvd player below it.
