2003 porsche wiring

Hello- I searched out all things Porsche here and did NOT find anything specific to my car. Please help before I am forced to take the car to someplace like Best Buys!!! I have found wiring callouts here for 2000 and 1999 Boxsters but my car is not either of them. My car is a 2003 911 Carrera Targa. It is the first model year of the fiber optic MOST systems but being that I am putting in all new stuff, it doesn't matter much. What I am need of is clarification of wires that I have and wires that I have not found yet. Wires I have but don't know what they do: grey/pink yellow/black RED / black brown BLACK/ blue green WHITE/ red black yellow Wires that I am looking for specifically: Illumination VSS Reverse ACC Remote turn on Power Ant (lead to go to ant. booster in pillar) I compared the wires I have in the car to the wire callouts on the schematics I have but the schematics do NOT tell me where they go or what they are for other than the Mute and Back Up wire. Please help. I am nearly complete aside from making the faceplate and running speaker wires. bob.

Specifically my car came with the High End Bose system, whatever that means. This is the CDR23 unit coupled with the sub and amp. I am putting in a Pioneer AVIC-Z2 and a JL Audio 500/5 amp. Later in the summer when the Visa bill is paid down, I will replace the stock speakers. For this application that I am doing, it was my understanding that the optic part is being worked around since I am not using the stock amp. The only digital connection in this car was between the stock head and amp which are both being replaced.

Oh yeah, I don't have a CD changer.
