The WG is plumbed to the hotpipe per some vacuum diagrams I've found online. Since the stock boost control solenoid has been removed, it's only one line with no tees.
People normally have the sender teed off the FPR line as you mentioned and the top right TB source to the SMIC BOV, but I changed things up a bit. The FPR tubing is 4mm, as is the BOV. The barbs are actually 5mm, but 4mm fits better than 6. Because of this, I decided to try teeing off the FPR line as opposed to using reducers and creating more potential leak points. I'm only hoping the top right and top left nipples provide the same vacuum source.
