I have one of these to fit to my 1997 facelift STi, pipework is different, anyone fitted one of these before. There is also a thread here answered by Jolly GG, I'm still confused, Needs fitting before a remapp.
I understand that the bottom is inlet from the manifold black plastic pipe, but confused after.
Thanks

 

top connection to compressor cover (ie. manifold / turbo pressure) middle connection to actuator and bottom to air intake.

If you have trouble I/we can fit it when I map it Andrew.
