What are they ? Where do they attach ?

I stripped down the upper and front engine to replace gaskets and o-rings last year. It's sad but I am just now getting back to reassembly and I am a novice. I have a good idea how vacuum and emissions go back together. Not sure where A & B plug though. Definetly could use help. Thanx

 

1. Connects to the breather tube on the passenger valve cover.
2. Should run to the charcoal cannister.
3. I think is the line that goes to the egr solenoid.
4. Emission hoses run there but not sure how.
5. Same as 4

A. Should go down to the sensor at the front of the intake manifold.
B. Should also go to the one sensor at the front of the intake manifold.

 

let me know if you need more help on this. I just had to do this because my mechanic bailed on me after taking my heads off. I know my way around chevy's but was knew to tpi's before this. I just finished mine about two weeks ago and can send you pics

 

Thanks for the help guys. I'm going to check it out this week. I'll take another look at it now I have a few pointers, system isn't crazy complicated but just cluttered. JAC113 pics would be awesome, I'll definitely let you know.

 

85IROC-Z, After reading your post and looking at it a second time it came back to me. Finished putting it back together in a few minutes. Need to replace a couple rotted vaccum lines off the canister and that should be all. After an oil change this weekend I'll try and start it for the first time in a year. Finally see if I know what I'm F#@n doing.
