ill keep it brief as I can, 1994 wrx import gc8 bought 2 weeks ago, the guy who had owned it had £8k worth of bills over the last 7 years but seemed to know as much about the mechanicals as I do currently!

ej20g lump I believe the early engine with 3 metal nipples on the inlet manifold, running fmic, bailey motorsport bov, standard td05 turbo, dash mounted gauge.
my question is:

Where do the 3 hoses connect too!
nipple 1 I believe is correct is connected to the boost control solenoid on the inner drivers wing? is nipple 2 the vacuum line for bov with a t piece to boost gauge? and 3rd line to fuel pressure? im aware I sound like a pratt but would rather have a crack myself before parting with money, any advise would help.
