Help! Airbag indicator stays on after window regulator replacement

[fab986]

Yesterday, I replaced my passenger window regulator on my 2001S following instructions from the "101 Projects for Your Porsche Boxster" book. After reassembling everything back I noticed that the airbag indicator light on the dashboard stays on.
This morning I decided to remove the door panel to make sure the airbag connector is securely fastened which it was. I disconnected the battery, disconnected the airbag connector to make sure the cable were secured inside the connector, reconnected the connector, reconnected the battery, start the car, airbag indicator is still on.

I'm at lost... I'm not sure what to do next. Any suggestions?

Thanks in advance.
