After changing the battery on a 2008 CTS I found a

hook up?

It's a battery vent tube, not a vacuum line. Since the battery is now in the passenger cabin, it has to be vented. The OEM battery likely had a hole that the tube plugged into, then the vent line ran out the wheel well. Some non-OEM batteries do not have the vent hole, so the tube is not needed.

I would make sure the replacement battery Does have a vent hole, if it doesn't you got the wrong one.

Thanks to both of you. Replacement battery had the vent hole and easily hooked up the vent line.
