a) Consider your ASCII art stolen.
b) I'm conducting a project to document the MB engine (MAC-12) in the absence
   of comprehensive documentation from Audi.  This is as far as I've got with
   the ECU part of the wiring harness:

Audi quattro - MB engine (MAC-12) ECU wiring

The  ECU is connected to the wiring harness via a  latch-
and-swing  connector.   With the  ECU  removed  from  the
vehicle,  the wiring harness connector should  be  viewed
with  the  plastic prongs on the right and  the  locating
lugs  along  the side of the connector at the  top.   The
upper  left pin is Pin 1, with numbering proceeding along
the connector to Pin 18 at the top right.  The bottom row
is  also numbered from left to right, from Pin 19 to  Pin
