Everything checks out with the ground wire and all connections. We even tried reinstalling the original wheel with the same results. No power to airbag, horn or controls. They're all dead.
Some Googling tells me we probably screwed the slip ring up when we torqued the wheel down the first time. Off to the dealer and hopefully they'll cover under warranty.
