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
35.
