If you're gonna flame me, flame on.

I am putting in a CD player and it's been a couple of years since I did this
and I have never done it on a VW (I have always coughed up $$$ to Circuit
City).  Ground wires in German cars are generally (1) Brown or (2) Gray?  I
have both and beleive it to be brown, but wanted to make sure.

Thanks,
Stefan

P.S. I don't mind if I get flamed for such a simple bit of info, but I don't
want my Van to get "flamed"  :-)
