Transmission vacuum line location

Question

I have 2003 Buick century 3.1 l V6 I put plugs and wires on it and I broke two backing lines of which I replaced but there was one that fell off that I couldn't find it's like at the disintegrated but it goes from the top of the intake down to what they call online the front side down about midways of the transmission and hooks on I can't find where it hooks on at
