Any vacuum like will likely work. They're all connected to the intake manifold somehow.
My guess would be to use whichever is easily accessible and closest to the throttle body.

How do I know what lines are vacuum lines? Could you give me a certain point that runs to the intake manifold? Thanks for the reply

Remove the plastic cover from over the throttle body and you will see a vacuum tree.
Any of those ports are attached to the intake manifold.
Beware though. It is not unusual for the plastic vacuum tree to break from age when fiddling with the hoses that are connected to it.
