I have found the following in working with VWs:

- Black = Switched (or conditional) 12v+ Power.
- Brown = Ground (chassis)
- Red = unswitched 12v+ (most of the time)

It's already a done deal but this may help other folks:

15/Black wire(s) = Switched (Ign ON) power. You have one of these
running from the Ign switch to the plus side of the coil, the other runs
into the Ign module. This is the Main Power into the coil and the Ign module.

Green (striped) wire = This the trigger from the Ign Module to the coil.
 (Collapse the Field! Collapse the Field!) From that side of the coil
there is also a:

Red/Black wire that goes into the fuse box. From what I can dig out of
the diagram it is the "Yes, Ign is ON!" lead for other parts of the car.
(Ign light in the Instrument Cluster,  fuel pump relay power, etc.)

Of course there is also the Main Lead out the center of the Coil to the Dist.

Fun part is when you find things you think are the 12v+ side of
something and find out it's really just a switched ground wire. (What?
Squeeze Me?) 

hth,

So remember, in German Red AND Black are (+) and Brown is (-).    8]
