I recently bought a w205 steering wheel online (picture attached) and I'm trying to put it on my 2003 R230 SL55 AMG. I was able to shave down the outer ring so the new steering wheel fits on my car. However, I do not know the wiring schematics (which wire controls which button the steering wheel) so I was wondering if anybody knew the steering wheel wiring schematics for the w205 steering wheel. Thanks in advance.
