I was trying to help someone here and was pointing them at a previous POS harness wiring diagram that I had done for the AAN. He came back and said only one AAN POS harness wire colour was the same on his ABY. As a result, I checked Paul N's S2Central.net POS wiring diagram which confirmed the ABY and ADU wire colours (NOTE: Paul's diagram says that the ABY, ADU and AAN POS wire colours are all the same, this is now shown to be incorrect).
Here is my version of an all inclusive AAN, ABY and ADU POS wiring harness colour diagram (useful if you are converting your ignition to 1.8t/2.0TFSI coilpacks or LS2-style coils as a DIY). The link to my POS information post (with internal links out to POS diagnostics and pin-swapping) is here:
