There's a switched power tap underneath the dash

The link I provide below points to a post that has a picture of this and includes directions on how to get at the place where you'll find switched, unswitched, and ground power taps.<ul><li><a href="https://forums.audiworld.com/a6/msgs/608511.phtml">Lots of info you don't need, but the info you do is in there.</a></li></ul>

So looking at Part 4 of that link

<center><img src="http://img.photobucket.com/albums/v739/hliu55/DVD/DVD53.jpg"></center><p>It states this with the pic:

I then disconnected the battery, and made the connections under the dash.
Red = Switched power to 75X
Black = Ground to main ground on left sidewall
Yellow = Battery to 30

There are lots of red, black and yellow wires...which ones? Also, does this apply to a B5 A4?

Switched power is on the ISO power block that plugs into the HU

On the B5 its definately there, referred to as "S-Kont" on the diagram (3rd one along from the brown earth wire), but with newer models they use the K bus, which is why you then need to source it under the dash in that link.

Don't know if this applies to B5 A4, but I would guess there's something similar in the same spot.

The key thing to note is that post "75X" is switched power. Ground is easy -- pick a bolt attached to the body. You can see one toward the left of the photo.
