Thanks Helmet, sorry I had not seen your post.
Are you referring to the european spec cars?
I can't find a proper diagram for them, but from what I can tell the only function for vac retard on them is A/C related.

On the aussie one, the manual seems to refer to B as the retard, unless I am not interpreting it correctly? The colour of the original vacuum lines is what I am using to make this interpretation.
