Pics of ZEX install?

[OneQuickGT1]

I am a little confused where these vacuum lines go to and from the ZEX unit. Does anyone have any pics of this setup? I am just confused, as one is connected to the FPR, the other to an empty vacuum port. That leaves the stock FPR hose out of the pic. I am assuming you plug that one into the unit? Any help would be appreciated.

Thanks,
Brett
