I changed the thermostat and when putting it back together couldn't remember where all the vacuum lines go, I need to see where they go.

Hello,

I attached the possible vacuum diagrams below. Depending on your specific VIN and configuration it may be different so I included both. Let us know if you need anything else!

Thanks for using 2CarPros. Com,
William

This is 1996 Buick century limited hose routing diagram added in the car, so. Is this a wrong connection?

If you are asking if this is wrong for a 2001 then I would say probably it might not be correct.
