Close but no cigar yet. It's the diagram that shows every pin that goes in the DME e.g. pin 80 = rpm signal pin 81 = ... etc
My manuals (pdf versions...) has everything except that! I have the 964 and 993 manuals and they have a very simple page with a view of the connector and next to each pin the function...

This, but for the 2001 GT3, is what I'm looking for (and it may be that it's very similar for the Gt3 to what is here below...)
