This is one line with three Ts it goes to the green and white solenoids. As well as the turbo control2 which is a Mitsubishi solenoid.
The highlighted lines are everywhere this one line goes. One goes down to the turbo actuator, the blue one goes to a vacuum chamber. It also connects to the turbo control 2. The other two connections go to the white and green solenoid. The line was also connected to a check valve that goes to the double throttle control
This is the turbo control2 solenoid Mitsubishi
This shows which sides of the green and white solenoids the lines connect to. (Highlighted lines)

More Hack Job
I don't have a solenoid purge control valve. My catch tank just goes to a check valve that's flipped the wrong direction to act as a cap. Should I get a solenoid purge control valve?

I think that three T line is maybe replacing a hard line that typically runs along the top frame of the rats nest, but who knows? Are all the harness plugs connected to solenoids? Are all, or most, of the solenoid vacuum lines connected to something, such as actuaters? Is the air control valve there? Are there three vacuum lines running to it.
Note: Those vacuum line diagrams are no scale or location exact. Some of those lines are actually very short and may be hard lines (at least part of the way).

The diagram says they should be
F = Charge Control
G = Double Throttle Control
H = Charge Relief
The only other differences that I have from the simplified diagram is that my catch can is only connected to the charcoal canaster and I still have the double throttle control connected, but its connected different. I also do not have the hardline of the rats nest that sits above the solenoids, instead my pressure chamber just sits loose atop the nest. Where should my pressure chamber mount?

Yeah it looks like someone removed some of the emissions stuff and didn't do a very neat job of it.
I would track down that purge control solenoid, it's worth having and they should be cheap and easy to find used.

Update
Update, I removed the rest of the exhaust manifold while I was in there. The gaskets to the block were fine but I picked up some nice used OEM gaskets from the exhaust manifold to the turbo manifold because mine were tearing on the inner edges and I didn't want that sucked into my turbos. I sprayed my gaskets with copper gasket spray for hopefully an even better bond. Luckily I didn't break any studs, good thing I ordered all new ones right? Much PB blaster was used! My turbo manifold has some cracking in it but the play in the turbos is ok. Pettit said I should be able to get some more life out of them and also gave me a price on having the turbos, brick and everything blueprinted and made nice. I plan to do that later when I can. I also plan to pick up a purge control solenoid valve from them next week. I took out most of the vac lines that are different from the simplified diagram and tomorrow I'll note down how all the different ones currently are set up for me. Then I'll assemble it following the diagram and I will also be reassembling my exhaust and turbo. Hopefully I can get it all done tomorrow. The vacuum lines is the most time consuming part. After these are finished it's an oil change and spark plugs. After this I'll be diving into the cooling system, raising the car a bit and softening the suspension (car came with pretty new adjustable bc suspension) , and have the boost lowered to 6psi while I continue to make the car right. I'm very grateful to all of the help I've received from both the forums and Pettit. I'm still very lost but I feel like I'm getting somewhere.

Does anyone know what I need to take out to be able to reach the vac lines that seem to go into the engine? I need to get to where dark blue and teal go into the engine. I'd like to take out as little as possible as to not compromise my old wiring harness. I started taking the solenoids out.

Does anyone know what this is supposed to go to? It’s just a hose with a bolt in it coming out of the top of the engine about where it connected to the trans. This view is from behind the UIM between the UIM and the firewall.

Errant coolant hose?
A vacuum line runs to the FPR in about that area at the back.
Look closely at the coolant flow diagram in the shop manual.

Which one of these two lines that I have my finger on do you guys have capped? I’m trying to find out which I plug the dark blue line from the diagram into.

I don’t understand sorry. I know it’s for the twin solenoids I’m trying to find out if it should be plugged into the spot that’s capped instead of the other one my finger was touching. Because the other one is bigger and I’ll have to stretch the hose to get it to fit.

Does anyone know if deleted rats nest solenoids can be unplugged? Mine currently are capped and plugged in but I don’t see why they need to be capped. I also feel like I should be able to get away with unplugging and pulling them out to keep as spares. I’m sure they’d last longer not in a hot engine bay.

The stock ecu will be looking for those solenoids and will be unhappy if it can't find them. Even if they are not actually actuating anything.
I wonder if your check engine light has been disabled.
Have you ascertained that you actually have a stock ecu?
Maybe I missed your confirmation of this.
In rare cases some folk stuff an aftermarket ecu in a stock box. In other cases the stock box has been customized with an added chip.
