Someone Help me/Everyone Have an Exact Diagram of this mani Fold Vac.
What Should go where.
I've searched and seen the FSM's and some other pics but can't really See each line Perfectly + I'm Not using everything Factory,Like ,NO Stock FPR or Charcoal canister,etc...but my car is a Lexus and has the Heater control valve so one of these goes to that.I'm pretty sure I have it Correct but Main Issue is What PORT does the Little DIAG Box hardLine go to Shown In black???
Heres some pics and if someone could Label Each Color to go WHERE,...That'd be Great [/Lumburg voice]:thumbup:

Black: Charcoal canister?? If I don't have one What should I do.Cap It? What about the VSV under The intake mani?Keep It or cap all those?

Red: Boost/Heater Control valve?
Yellow: Supposed to go to Stock Bypass valve (I'm Using Synapse bov)
Green: Power steering assist Valve
Blue: FPR

been looking for the answe to this question for a while so BUMP

i know the smaller metal vac line goes to the charcoal canister and the one that goes on the fuel rail is fuel return and the last one is what im not sure of but i think it goes to the big nipple on the inside of the intake manifold.

i t'd the red and yellow for the my after market BOV and am using the small nippile on the inside of the manifold for boost guage.

i havent cranked it yet but i sure hope im right

Interested, as well. I'm going to be running the same setup. No charcoal canister, aeromotive FPR kit. But I'm running stock twins (for now).

Black goes to the charcoal canister. Everything else you've got correct (yes, red is for the heater vac).

That's good news. I'm not using the charcoal canister, or the heater vac. I'm sure I'll use one of those for the boost solenoid, but don't know what to do with the other one.
