I have 2002 C240 and bought cd changer(A 203 820 90 89)model MC3010 on ebay.It's suppose to mount in glove box but found fiber cable in trunk with 4-pin power plug. Unit has 3-pin connection.

Is a 3-pin connector in dash at radio? If so, how do I connect.
What's installment time or would I be better off to get dealer to install?[:(]

My notes say that the 3010 is the right changer. Not sure about the power plug.

I think I would check with a good auto stereo shop before I would let the dealership touch anything.

Good luck.

Yes , I have the AUDIO10 CC and the MC3010.
There is no power plug behind the radio on my C220CDi !! and I don´t know how to buy the power plug and how to connect it
I have seen on the web that power plug has a brown cable is (-) , a black one which is (+) and blue one which is the "wake up signal " , but where do I have to take the wake up signal ?? ( from the radio?), and what is the color?

Come on, the head unit does not work from holy spirit, it must have a power plug. You probably mean it does not have a power connector for the CD changer. That is the case.

Most wakeup wire colour is PK, pink.

I had a look on the web and I have founded that "C connector" on the back of the radio has 10 pins :
pin nº 4 is wake up ( blue)
pin nº 5 is + ( black)
pin nº 6 is - ( brown)

Any confirmation to to build my cd connector

Concerning D2B loop , I need to start from the red light in the Audio10 ---> goes to the rear of the car ( to white light ) , come from "red light" fron the rear of the car ----> need to go to the white led of the CD , finally red light of CD to the white of the radio.

Is it right ?

Could you post the exact car model you are working on. I believe I looked at the wiring diagram of a C220 CDI assuming this was your car.

Which reference did you use for the blue colour?

My car is a C220CDI.
I need the power plug connector for the MC3010 ( A203 820 90 89) ,
this power plug has 3 pins . this connector has 3 pins , 1st pin is brown cable (-) to be connected on pin 6 ont the C connector ( Audio 10 ) , pin 2 is black cable ( + ) to be connected on the pin 5 on the C connector , and pin 3 is a blue cable ( wake up)to be connected on pin 4 on the C conector.
My difficulty is to find the power plug .
Is somebody able to tell me if it is A029 545 55 28 ?
This is my main concern actually.

I understand your main concern but I would like to be sure others get the correct info about the rest that was discussed, including myself.

This part you refer is no wiring harness but just a pin bushing housing.

There are six different 203 model C220CDI cars, if wagons were included. That is why I was asking more details.

On the wakeup wire, perhaps I was looking at a W211 (more natural for me), looking at a 203.008 car I find the wakeup line colour being BUBK, not blue but blue with a black line.

I'm guessing you would need parts:
A2035403234 and A2035400809.

Edited: I figured out you may have been after the connector housing actually instead of the retrofit wiring harness, probably going to build the cable yourself.

My C220CDI is the w203 Sedan version ( March 2004) , sorry for the missing . I have finally bought the A 029 545 55 28 part . This is the pin housing but perfect to make the connection with 3 cables.
I will start to mount it this afternoon.
Will let you know if it works.
