I think most of us wants to know the bose amp and MCS unit wiring diagram on the Fiber 03/04/05 ML so that we can do a DIY audio upgrade. I know my self is. Can someone share the wiring diagram if one is available. I don't want to start mess with electrical unless blueprint is available, otherwise, most likely I will short out the electronic circuit.

Thanks.

It was all trial and error when I did it. I am not sure the wiring diagram is out there. I know the pin out for the 2000 ML on wolfgangs page added some benifit. I will keep looking for ya.

I put together a PDF file with some stuff I found on my service DVD. Though there is no way to post it here. If you give me an email address, I can send it to you today.

John,

I just sent you another attachment by email..

I combed the MB Service DVD and there was no specific reference to
the bose power amp connector. Though, I am hoping that the harness that
connect the amplifier to the radio will have a similar pin correspondance, and
the back of the radio plug has it's outputs described in one of the notes. I
wonder if that may help...

I wonder if somebody else have access to more detailed information...

got the PDF,, thanks. It is more about installation then wiring diagram.
can you take a look at the electrical session, they might have wiring diagrams in that section.
Thanks.

John,

I just sent you another attachment by mail. It's a large PDF, and the component A3/12 (Sound Amplifier) is all the way to the left of the diagram. You need to pan the image around in order to see parts of it.. Let me know if this diagram is what you were needing... The sound amplifier diagram coordinates location is: 63/A

Bingo, the diagram on the right hand side is the power amp. Looks like a 6 channel output according to the diagram.

What about the wiring diagram for the head unit?

thanks.

What part of the head unit..? The diagrams in the service DVD are not easily searchable, and they are all kind of partial diagrams around. I wish MB will add more logica ways to search for component diagrams..

ML500 2003 MY04 Radio replacement.

It is very easy, a lot of people and a couple of installers said it couldnt be done because of the fibre optics, (1) pull radio out, and hang onto plug on back and pick up power, Leave the fibre optic wire in the cavity in the dash.then (2)Also leave the fibre optic wire there also. remove amp from fire wall under windscreen, may need tin snips to cut tin bracket holding it up there, to get to it unscrew and remove kick panels above brake pedals, then locate the plug on the amp and unplug, pick up the speaker wires and wire to speaker wires on back of new radio. Join in your new amp, I bought a 4 channel amp 2600 watts of ebay for $100.00 works great, and installed it under the drivers seat. The only thing is you loose the little spaekers in the rear pillars and the sub under the passenger seat. I have a china 7 inch DVD CD digital TV bluetooth, am fm GPS the whole thing and it works great. Hope this helps.Any more questions email me . by the way I put mine on LPG as well so it is a s cheap as chips to run. [email protected] 200
