Hmmm.  Interesting.  I'll have to look at the diagram more.  I would 
note that for some of the 80/90s, VAG 1551 can be hooked to the fuse 
holder on the fuel pump relay to initiate, store and display the codes 
generated.  This is indicated for pre rapid data transfer vehicles.

Have you ever seen the factory diagrams?  The base diagram for the car doesn't 
include things like ABS, a/c, etc. - it just indicates where the connectors for 
them are, and doesn't even list the two wires in each connector side by side.  
It's a needle-in-a-haystack job.

The fuse block wire, however, is (at least on the MB ur-quattro) brought up to 
the electronic dashboard as pin 33 on the 35-way connector - it seems to be the 
ECU's control for the warning light that is used to tap out the codes.  It's 
black/white around the fusebox, but becomes gray/brown on the way.
