420A 420a Vacuum line help

[Ricecar]

I'm sorry if I missed a different thread explaining this but I didn't see anything helpful to me when I searched for a while.

I'm extremely confused with the vacuum lines in the back. I'm installing a replacement engine and I can't set it up because I have 2 lines to connect (I think) and I don't know which line comes from. My car doesn't have cruise control so I figure I'd block off that but a person said the middle port was for cruise control but the diagram I found says otherwise. The other vacuum lines are coming from random places and I didn't know which one has to be on the left, right or middle.

The last engine in this car had an aftermarket intake and it's just confusing trying to revert it back to stock parts. I did try researching but all the links from 2005 don't work any more thanks for any help.

this one is saying the middle is cruise control, I don't know why they are different. Each one needs to be connected to its correct spot right?

If you're referring to the 3 way vacuum fitting, it does not matter which hose is connected where. They are organized in a specific way from the factory for organization purposes as you can see in the diagram but the whole fitting has vacuum. And that looks like a 95-96 diagram because the 97-99 FPR is not mounted on the fuel rail. The 97-99 had 2 of the vacuum lines connected to a black vacuum reservoir behind the intake manifold which then connected to the cruise control servo. So if you do not have cruise control I would think you only need to have 1 line for the EGR connected to the 3 way fitting. Is that the case? If there is another line, trace it back and see where it goes.

I saw a vacuum line hanging off of the EGR solenoid, and I believe I have 2 coming out of both sides in the engine bay, I'll get pictures tomorrow to see if they are even what I am thinking they are. I'm new to a lot of this stuff, owned eclipses for years but I got a fast and furious replica that had a blown headgasket so it's my first time replacing an engine. I'm still trying to line the replacement motor up to the motor mount and transmission. It was a fight to get it in with how tight the engine bay is and now it's a fight to get everything lined up. I really appreciate the help to ease my worries about the vacuum lines, one less thing to stress about

If it's not too late, unbolt the clutch assembly and install it on your input shaft first. The biggest trouble is getting that to mate up so I usually leave the clutch inside the trans when pulling the engine

I'm not sure if I understand, the transmission is still in the car and the plan is to sandwich the engine and trans together since I have it actually in there now and then I'll put the 4 clutch assembly bolts in. So I think I'm doing it how you explained. Thing fell out when I was getting the engine in, glad I realized and threw it back in there before I finally managed to get the motor close to being in place is the input shift the splines I slid the clutch assembly onto? Should I get the transmission all hooked up before messing with the motor mounts or motor mounts first?

I saw a reply you gave someone else about the egr solenoid line being broken and them having a vacuum leak that way and mines broken as well is there a way to block it off without the plates? Also the replacement engine has a box underneath the intake manifold and that have vacuum lines coming off of it and also one at the top going across the intake and throttle.

sorry about the poor quality but here is a line coming from the left and it has a t adapter with only one side with a line.

I'm noticing the clutch is spinning with the flywheel sometimes like it's tight up against it on one side. Im also seeing a transmission bolt hole at the bottom rear, how many are meant to be at the bottom? There another hole but that's underneath the flywheel area. It's definitely still spinning in there though and sometimes the holes will change alignment so I don't think it's crammed against anything too bad if it can still spin, but definitely looks uneven, I know we are off topic for the thread but you've been super helpful so I figured I'd ask

If you want to remove the EGR without using block off plates, just eliminate the vacuum line coming off the intake manifold and cap off the fitting. Without vacuum the valve will never open. You will probably get a check engine light though. I'm also unsure that I understand your issue with the clutch.
