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,

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.
