On the left side of the globebox, you should be able to see the perforations on the left wall. Use an exacto knife to cut this out. The power wires for the changer are either taped in the area behind the radio or tucked beneath the carpet on the passenger side. Route the power wire through the hole you made and plug it into the changer.
The fiber cable is in the trunk beneath a panel between the spare tire well and the rear seat. There are several.
