FWIW - Some digging showed a possible bad connection under the passenger seat - so I reconnected the yellow connector which is ALWAYS for ANY car yellow, so if you have other issues with any car, unplug and plug back in this connection.
I haven't had any airbag light flash since this - could have been loose.
Will keep an eye on it. Drove to work this morning 35 minutes, and no light. It would have went off typically in the past by now.
