Default Correct vacuum line locations?

Attached some pictures here. Each of them has 1 or more arrow. Just wondering if these are where the vacuum lines are supposed to go? 97’ GE engine if that helps….

the first picture that hose goes to that nipple yes.
the second picture looks like the line for the charcoal canister, I can't remember maybe it goes to a hardline under the Y crossover pipe so look for an unused hardline. You may want to look for the vacuum diagram sticker on the hood I think there should also be a check valve on the vent line unless it is another line.
the third one looks right but check whats going on under the Y part of the intake manifold if its been modified or not.

There was only one hard line left under the Y pipe and I confirmed it’s location through another source already. Picture 2 can only go in that spot. Wondering if I crossed it with anything by mistake. Hope not.

You would have to pull the y off to see the lines underneath, I think that is where the little plastic check valve is also but I can't remember what a stock one looks like now.
It's probably in place if no one has messed with it though I would guess, connect it and see how it runs.
