I have a 2005 chevy tahoe which has an overhead rear airconditioning control panel mounted on the roof just in front of the rear seat. I am interested in pulling that out and mounting an overhead dvd player instead. I was wondering if any one out there can help me out and advise whether I can tap in the wiring harness to my dvd overhead player to the existing wiring harness that supplied the airconditioning controls? Oh, by the way the unit that I want to install is the Audiovox 10" dvd player (auxmtg10ua)
