Alright so, I've removed all of the emissions equipment off of my single cam and like a dumbass, I didn't take pictures of how to route all the lines and shit back together.. All that is left is the FPR, IAA unit, and air regulator. I don't know what vacuum and coolant nipples to block off and how to route the new vacuum and coolant lines.

halp pls

Pictures:

Correct me if I'm wrong with any of the following:
#1 - I don't know. Looks like it's for vacuum.
#2 - PCV valve. I believe it connects to #16.
#3 - I don't know. Looks like it's for coolant.
#4 - I believe this is for the brake booster.
#5 - Not sure. I believe its the vacuum source for the FPR.
#6 - I don't know. Looks like it's for coolant.
#7 - Inlet for the air regulator. I'm guessing it's for coolant but I don't know the source.
#8 - I don't know. Looks like it's for vacuum.
#9 - Coolant nipple for the throttle body. Not sure what to do with this.
#10 - Same as #9.
#11 - Inlet for the IAA unit. I'm guessing it's for coolant but I don't know the source.
#12 - Upper radiator hose.
#13 - I don't know.
#14 - I don't know.
#15 - I don't know.
#16 - I believe this connect to the PCV valve, #2.
#17 - I don't know.
#18 - Lower radiator hose.
#19 - Heater hose. Not sure what to connect it to.
#20 - This was left over from when I removed the AIV unit. Not sure what to do with it.

And then there are bunch of random lines I pulled off. Not sure if I still need them or not. Also, I'm not sure what to do with the bundle of vacuum hard lines behind the valve cover. I don't think they are receiving any vacuum so I guess it's ok to just leave them there.

Any help is greatly appreciated even if it's just identifying what to do with one of the numbers!

Thanks!

Alright so I've gotten most of it back together, and I'm about to buy the rubber hoses. One question though. You said that the metal tube (labeled with A and B) connecting the IAA unit and the air regulator on one end is supposed to connect to the intake elbow on the other end? I thought those two things were supposed to receive coolant, not air. Just looking for some clarification.

I'm almost done, big thanks to KiLLeR2001. I just need to find some hoses that are capable of bending around 180 degrees without pinching. There is a lot more information out there about the KA24DE so you shouldn't have too hard of a time. Good luck to you as well! I'm in Georgia too btw. Are you on 240Atlanta?

I have a couple quick questions.
http://tehl33tsite.com/240sxdd/help/N12qHcJ.jpg

What do you do with the bottom set of piping? Can you just take it out, as it does not seem that it is needed?

The set of smaller pipes in the back of the block that have 3-to 5 pipes coming out of the back, looks kinda like a spider, do I just plug those? Also those seemed to be linked to some plugs on the top of them, they were disconnected off of my engine, do I plug them back in or just leave them unplugged.

The last question I have is about the solenoid that looks like it is below the throttle body. May not be a solenoid, not exactly sure what it is. There is a plug that runs into it and two pipes running out of the bottom and looks like there is one that needs to go in the top. Sorry, I did not get my picture yet and will get it shortly to clarify things.
