Fetrotech Tool Mercedes EDC16CP31 Pinout

Users found a few different pinouts for this ECU and none of them worked.

Solution:

Please see attached for Mercedes-Benz EDC16CP31 on fetrotech.
Use this top pinout

pay attention to the gpt wiring, as we found the colors on the pinout we used do not match numbers. Opposite to each other.

It is working now. Fetrotech tool read and write no problem
