1995 S320 CD Changer Connections

Hi, this is my first post here as I just bought my first Mercedes. I was told it is prewired to mount a CD Changer in the trunk. The person told me the wiring is under the carpet in the trunk. I have looked but can't seem to find it and I am not wanting to tear up what appears to be underlay on the left side of trunk in case it is not there. Could anyone verify or give me at least a hint as to where I should or would find the wiring setup for the connection of a changer please? The stereo does have a Cd button on it so I presume(hope) that the connections are somewhere in the trunk
Thankyou for any insight and help in this matter.

The only CD Changer you can use is OEM. A basic diagram of the 92 W140 can be found here :


So if it didn't come with a CD, you'll need a few extra cables, and connectors.

My 1994 S500 coupe was bought with an aftermarket Alpine CD/radio.
I have sourced a Mercedes Radio/Tape unit (model 'Special') that I believe is from a 1995 car and a Mercedes CD Changer (model MC3194) from a 1995 W140 sedan.

Does anyone know the part number for the cable to connect the two?

Thank you in advance.

In the past:
'76 280S, '79 350SE, '80 230e, '82 Audi 200T, '84 280SE, '85 280SL, '86 230TE, '?? 300TE, 89 560SEC, '92 500SL, '94 S500 Coupe, '96 S320, '98 S500, '00 CLK320, '02 S500, 03 VW GTi. Fair to say we fancy German and Mercedes in particular!
