Audio Systems: Adding iPod, Mercury Montaineer iPod, ford iPod interface Ford iPhone integration

Question
How do you get music from a 4th generation iPod to play on a stock radio with jbl audio on a 1997 mercury mountaineer?

Answer
You need an iPod interface, or iPod integration for Ford vehicles,
in your case this plugs into the amplifier on the rear right side behind the plastic panel,
you can also buy a CD changer cable and connect it in the center console
