Hey Joris.
Yes I figured it out. I will try to make a pinout when I have a little bit more time

I need al little bit help with the pinout of the Green ecu connetor C131.
I have found some info on the net but not an clear pinout of this connector.

This info I found was wat I believe for OBD2a (96-98)
