4-channel Bosch 5 ABS with EDL to Coupe

[Error404]

I can see the benefit for the front axle, but surely with a torsen rear diff and the EDL braking a spinning rear wheel the torsen will divert more torque to the braked wheel, not the opposite wheel as with an open diff.

Attached is some info that may help. There's a spreadsheet showing (rather cryptically) what connects to what, a wiring diagram that's the closest I could find to the UrS6, and some notes about the UrS6 ABS harness.

The A4 diagram in your zip is very much the same as the 1997 A6 quattro one that I suggested (pg. 45/48 of http://12v.org/urs/1997_Audi_A6_Syst...g_Diagrams.pdf)
