the fiber optic wiring is on the right side of the trunk where there is a well.. that is where the cd changer is mounted. you need to remove the right side trunk lining. you will find the fiber optic wire just right of the well. mine was tuck down in the corner..kind of have to dig a little. the power supply wire is bundled together with a bunch of wires just above the well towards the rear seats. i had to remove the nylon ties and search a bit for it. once you remove the right side trunk lining it will be alot easier.. at least it was for me. took me about an hour for the whole process. hope this helps. i got my changer and mounting kit at autoclass.net
