96 opti vac line routing?

[grandkodiak]

96 lt1

There are 2 connections on the opti drivers side, one top, one bottom, for vac hoses...and i have 2 hoses, one with blue/white valves, and one without. i found the pic below so i know the one with the blue/white valves connects to the intake manifold by pcv, and thus the other hose connects to the intake tube... but which ones top/bottom on the opti itself?

ie. intake manifold to top or intake manifold to bottom, and intake tube to top or intake tube to bottom.







ps. there is a vac split on the intake manifold... where does the other line go? its not pictured on shbox.com, and its too tight back there to follow if with your fingers unless you remove the tcs box and mounts...which im not doing. its hard plastic and goes stright back then maybe down towards the back of the motor.
