assitance requested with wiring a radio ina 1991 300

[CJ]

I am hooking a Sony Cd player into my 1991 300D.
Here is what the wiring looks like on the back of the unit form left to right:

ANT-antenna

BLUE-power antenna

SOLID GREEN-????
BROWN w/VILOET-It appears to be a ground

BROWN-ground
BLACK w/YELLOW-acc
GREY w/VILOET-????
RED-12 volts all the time

In addition, there are two pill-shaped plugs marked L & R, with wires coming out of them as follows

LEFT-BROWN and BROWN w/green
GREY and BROWN
RIGHT-BROWN and RED
BLACK and BLACK w/RED

If you could explicitly tell me what thee wires are for, that would be greatly appreciated.

Thanks in advance for all of your help!!!
