[Dmitry at Pelican Parts]

Hello - I was able to find the below info from an older thread - this was referenced for a 997, but I would assume this is also the case for 996s:

If you are in the USA the cars do not have the anchors installed from the factory. You have to go to the dealer. There is a kit that includes the anchors as well as the air bag shut up switch,--all must be installed at the dealership.
