And it's part # 444 907 388.  The ABS controller changed in the ur-quattro at 
VIN 85-H-900252 and the part # 857 907 379 acquired a "B" suffix.  I can't see 
that the wiring loom changed, though, and a _lateral_ accelerometer was always 
fitted to Sport quattros.  Perhaps this connector is present on more cars.
