M272 ECU harness wiring diagram

Can anybody refer to the place where I could find M272 engine ECU harness wiring diagram?

I have weird issues with my 2007 R-class acceleration circuit. CEL continuously pops out, scanner shows gas pedal sensor issues. Gas pedal was replaced with no change in the behavior.

When connected to a computer it shows that both sensors are read correctly. My indie mechanic suggested that wiring connecting pedal and ECU must be checked. I could do it myself but have difficulties finding wiring diagram for the ECU harness.

If somebody has it, please help.
