Pat:

Wiring harness and plumbing.

the 3b uses the same style harness connectors as the B3 Audis.

the AAN uses the same as the B4

The plumbing is different for the AAN which means that may need to modify 
the IM, move the CQ radiator ( angle it so that the intake and TB clear the 
radiator) or replace it with a 3b/S2/ or front mounted one ala MTM, SQ, or 
Wagner....

You also need to deal with front snub mount issues amongst others (3b is a 
drop in, AAN uses a different location due to the AAN having a front 
mounted radiator and different style front cross member...
