Where do the Vacuum Advance hoses attach to the intake? Pretty sure drive side..but there are 2 possible places.. which goes where? or does it matter?

thanks.

ok.. got 1 of 2 lines.. line with filters etc goes to intake vacuum, just to the right of the pcv

Where does the other line go??

There is no vacuum advance on a LT1.

sorry.. whatever the 2 lines from the opti are.. i assumed vacuum advance.
