blaupunkt preamp adaptor

[qza]

I know several people have installed the blaupunkt adaptor to run an amp off the stock HU. I ordered the blaupunkt preamp adaptor and went to car toys to have them pull the deck and install the adaptor. They told me that without a diagram then they can't do the install. They said it was too complicated and didn't want to hook the adaptor up wrong and destroy my stereo. I was just wondering for those who already installed the adaptor, what did it entail? Does it just plug in or did you have to modify it? Also what are the two random white wires that are not hooked onto the adaptor plug? BTW I have the stock non-bose stereo in a 2002 audi a4.

Any help would be appreciated.
