Audio Wiring Diagram

I just bought an '02 C240 with standard (Audio30) HU and optional Cd changer. My RR door speaker does not work and I have concluded it is a wiring issue, since the speaker itself works with an alternate input. I am looking for a wiring diagram from the HU to the speakers so I can work through the problem and find the break. Any help would be appreciated.

Enjoy!

However, in the future, please utilize the search function. I know this pdf is out there on these boards, since I found it there myself.

JedCred, WADR, I STFF for several days for the info and nothing came up on the wiring diagrams. If you were able to find it once, surely you could have found it again - and it is that link itself, and not your recollection of it, which would have been appreciated. Thanks anyways.:stick

Actually, I went through the effort of finding the diagram, posting it on my personal site, then providing the link for you. If you don't appreciate my very gentle way of helping you and reminding you to search, then I have one thing to say that everyone else would, a single line post.

STFF.

Now click on the word Enjoy, and get your wiring diagram.
