im working on a 85 iroc and i had to pull the heads off and now cant rember where a few parts go. 1st off im looking for what hooks to the back of the fuel rail on the drivers side, theres a sensor that goes in the center of the intake with a thin tube that runs toward the back of the fuel rail but i cant seem to make it fit. it looks like it goes there but can get the tube in far enough to get the nut on, is there a rubber o-ring in the way or something??

2nd i need a diagram of the egr set up on this thing after i took the air pump and air conditioning off i now have extra harness connectors obviously but i need to know how the egr hooks back up. i should of taken some pics but thought i had a good memory lol. thanks in advance

UPDATE: i figured out where the tube goes and it did go to the fuel rail i just had to pull the o-ring out of the inside of the fuel rail.

does anyone know where all the egr stuff goes??
