I pulled my eninge out to install a new flexplate and cant remember how the throttle body hoses are connected. Haynes manual and a VW diagram of the vacdum lines and coolant lines are useless...im stuck on this one issue...went all over the state trying to find a v6 at a junk yard to take a picture of...no luck

We ultimately can get you all hooked again but...
What year car is it you're working on?
We'll need to know what engine you have. It looks to be an ATQ engine code. Can you confirm that?
There were (2) engine codes AHA and ATQ, both engines had emissions revisions during production so getting everything right for proper connections might take a few postings to get all the needed info.

Assuming your car is all original factory, the engine code is visible on the passengers side (right bank) cylinder head on the inside front corner.
There is a tab/lug that sticks out that was engraved from the factory with AHA or ATQ.

Below is a 1.8t 4 cylinder engine with the tab I'm referring to in the circled area.
The v6 has that same tab in the same location. It is clearly marked on the top flat surface.

ATQ. Got it.

Don't' sweat it, everybody's gotta start somewhere sometime.
Unless somebody beats me to it, I'll post up some pictures of the ATQ vacuum / EVAP system that shows what goes where.

Are you talking about the bracket that is next to the power steering reservoir? That gaping hole inside the bracket, is just that. Some cars had something there, some did not. Unless somebody was modding your car before you bought it, I'm willing to bet you it came that way from the factory.

Yea...i saw some cars at the junkyard that had a silver canister thing there....but they had a different engine too
Exactly.
I'm not 100% sure but I think that silver canister was part of the EVAP system on the older AHA engine code vehicles.

Just some FYI,
If your new to Passat's and plan on owning for a while, a Bentley manual (mostly all inclusive shop manual) would be a worthwhile investment.
Only $150!!! A single avoided trip to the dealership or garage will cover the cost of the manual and then some.

Here is all I have available. If I recall, the suction pump goes under the vacuum plate in the 1st pic to a short hose connected to the intake manifold. I don't have a V6 at home, but I might still have an intake manifold I can get a pic of if it still has the suction jet attached.

Here is another pic from the side:

The pics were on a later model ATQ, so the PCV is slightly different than the 01.

That was one of my questions I wanted to ask.
Do you have the round black valve? Looks just like a hockey puck. I'm guessing not.

I don't recall all of it, but the the bottom of the F shaped hose goes to the brake booster. The suction jet goes to the top. The side pipe off the suction jet goes to the PCV. The green goes to the middle of the F hose.
Thanks to Ashman's writeup (with pics) here:
