hey everyone, i need some help. i have a '93 honda accord 10th anniversary edition. it has an airbag on the drivers side steering wheel. my bro was driving it around, recently got his license, and got in an accident and the airbag deployed. i rolled the airbag back up and put it inside the steering wheel and taped it all up, but that looks really sh*tty. i found on ebay an airbag:
Airbag

1) how do i go about taking the old airbag out?
2) how do i put the new airbag in?
3) do i need to get a new airbag computer and swap it w. the old one since my airbag deployed?
4) if yes to (3) where is the airbag computer and how do i replace it?

thanks in advance. i could use any and all feedback at this point.
