(Edit: I found the vacuum diagram and figured out all of my issues. See my reply to my own message below.)
Okay. So, I replaced my clogged PCV system, got the banjo vent unclogged, got the damnable banjo bolt tightened, and have the intake manifold reinstalled properly. Unfortunately, I have some hoses that I don't know how to properly connect back to where they belong.
Please look at the pics below. The last one shows the Evap Emissions system on my '98 but it shows the hoses with the T-connectors in the upper right identical to those on my '99 T5. These hoses were toast on this car. I need to get this hose connected to the proper places. I am thinking that C goes to the Vapor Canister Purge Valve by the radiator shroud. I'm thinking A goes to the big nipple on top of the intake manifold. I'm thinking that B goes to a check valve coming from the back of the engine (6 in crude sketch below).
Here's the basic picture (or crude artwork):
So, 5-6-7 connect with check valves flowing toward the manifold. Right?
Does elbow #2 go to the nipple on the big ETM intake pipe?
That leaves me with that small nipple #4, and I don't have anything to connect to that. I'm at a total loss on that one. HELP. Looking at the blue sketch, could elbow #2 go to the small nipple #4? Then what about nipple #1 on the ETM intake tube? I'm definitely missing something, here.
I think this is an S60 manifold that I have added the two nipples to look like my T5 manifold.
This is (I think) the hose assembly from an S60, but it is very similar to mine.
Where do these hoses go? Help!! T5 '99 Vacuum Connections

Found this diagram which answers all of my questions. I'd seen it before, but now I understand what it's saying to me!
I actually wondered whether that small nipple could go to the turbo because I have a line like that on my '93 940. Somewhere there's a little vacuum hose hiding amidst all of the other black rubbery things. I'll have to hunt it down.

That doesn’t look right for a 99
Is your Evap canister under your front fender or in the back?

I believe we had a bad diagram for part of the year... Remember the fun on my XC with my U instead of J hose? =)

Yeah, my 1999 has the 1998 sticker showing an FPR! Good luck finding that on ME7!

In my '98, it's in the front. Reportedly, '99's have it in the rear. For my '99 T5 S70, the under the hood components seem to be exactly like this. There are an awful lot of variables between these P80 models. Anyway, I hooked things up per this diagram, and the car is running great regardless of the physical location of the components.
I found a lot of bits that had been in place perhaps since the car was new, and had to replace them all. This included one evap hose that was split up the side for about 4 inches and just about all of the plastic wire loom shields. Had to replace just about all of the latter.
Oh. And I have found red Loctite in strange places on both of my cars. The intake manifold bolts had red Loctite on them but the mating surfaces were not properly cleaned when it was used, so they came out easily. On my '98 V70 with the canister in the front left fender, the long bolt that secured the canister was reassembled with red loctite, and that was clean enough to hold. The long bolt snapped off on me, and the canister is now secured with tie wraps.
