General Maintenance & Repairs - HELP: switched from ls1 intake to ls6, vaccum question??

so i switch from a 98 ls1 intake to a ls6 intake off a vette.
cant seem to figure out the vaccum lines, that Y off in the back
(mine was melted in half so i plummed one up of my own.)
ive searched and searched but cant figure it out.
plus since mine was melted and disconnected before i messed with the intake (no wonder it idled at 1100rpms, and didnt run right....) so i have no idea where it goes
all help is greatly appreciated.
my car is my dd and need it back an hour ago lol.
thanks!

Mine is an 01 and looks like this, I don't know if 98 was different but hope this helps.
