Don't quote me on this but I think the best way is to remove the glove box compartment which will give you the space to get behind the dash. You will then be able to see the airbag module and connectors. Separate the airbag connectors and the module should be attached to the dash by 4 bolts. Once these are removed then the module should pull out.
As you stated before make sure the battery is disconnected and make sure when handling the module the exterior trim plate is always facing away from you.
I would wait for a second opinion of somebody else first mate before attempting to remove it.
Good luck
