Can't help, Mango, but came by to lend you moral support.
Hope you find out how to find out the proper location. Not having done this myself, I only have a vague understanding of it. Fortunately, though, when I do do it, I know where it'll go, coz, you know, I'm boring!
I'm so depressed. No one wants to come see me. :(
Mangofy your E46!
