1JZ Vacuum Question. VERY SIMPLE

[BigTSetter]

Ugh, for the life of me i can't find a diagram on where this vacuum hose goes.

Rear of the intake manifold. Has two nippels. One according to the diagrams that i've seen is supposed to be Block Off. However, where does the other one go?

I'm thinking it hooks into the BOV but i could be wrong on that.

If anyone is confused, take a look at Ricks diagram:
Fig. 1
Fig. 2

As you can see in both diagrams it's the very rear/side vacuum line connection. One is blocked off in one pic and the other nipple is left open.

Any help would be great.

THanks

bryan the big one in the back goes to the bov througth the line that is on the air tube at the back of the head.the other line tee's off to the pressure sensor for your boost gauge(if original is used)and the heater valve
