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.
