Disconnected my battery to be able to remove the airbag safely to remove the steering wheel to get it nicely re-upholstered. Followed a YouTube video that shows how to do all that but have the following question: do I leave the battery until the wheel gets back to me (about a week) or can/should I reconnect it the battery so that other stuff gets some juice? (I won't be turning the car on or anything in the meantime)...I just don't know if I will only lose my settings (radio, etc), or if this will mess up the ECU too.
Thanks.
Thanks.
