How do you change to an aftermarket CD player in a 1991 Dodge caravan?
Visit your local Best Buy store, they have a mounting kit that adapts an aftermarket CD player to fit the opening. They also have a wiring harness that plugs directly into the factory wiring. You will have to solder the wiring harness to the CD player, but this is the best way to go. If you follow all of the directions the install will look like a factory installation.
