Hello! I need some urgent help with this vacuum line. I have searched it everywhere, and have an entire FSM printed out. I am pretty sure that the SR depicted in the FSM is not the one I have, since it has EGR stuff on it. This is the diagram in the FSM....

So here's the deal. I have a FMIC, and an HKS SSQV. I found where every line hooks up to, except the one circled! There is no nipple on my OEM intake hose for this line. I figure it's because I am using an S13 intake hose, not S14 (I could not make the S14 hose fit, since the motor is in my S13 chassis. I forget why, I think it's the way it's routed stock) Now... I know that this line is hooked up to somewhere that has both vacuum and boost. Is there any other place I can hook it up to? I do NOT want to do it all haggered. Not T-ing off anything important, such as the FPR or anything like that. Thanks in advance for any help! :)

Someone on SON240SX.org mentioned that the line I have circled is the "reference signal" for the wastegate. They said it can only be hooked up to a BOOST source, NOT vacuum. Anything before the throttle plate should be good, no? There is also a "capped off" nipple under my TB. I am thinking about using this for now. Any thoughts?
