Volkswagen: 1992 vw passat, vw passat, lighting circuit

do you know the radio wire diagram of a 92 vw passat? i'm trying to install an aftermarket radio. also all the speaker sizes.  thanks

Answer
i will look into those for you tomorrow and reply by tomorrow night as i do not have access to full details tonight.
Generally the speaker connections are the brown plug with 8 wires in it. the connections are usually inner cables for front and outter for rear.  so with the plug on it's side, the two left ones are a rear, the next two in are the same side front etc....
the power supply plug usually consits of, brown or black eart. 12v permanent feed is usually red. then you have upto 3 others, a 12v switchable live (for on off function from ignition barrel), a switchable 12v feed from the lighting circuit, and a wire for a power aerial. if you send me an email to john_dempsey82@hotmail.com i will send you the diagram tomorrow.
