The guy at the wrecking yard helped with the airbag.......it was kind of a PITA. Be sure to disconnect the battery at least 15 minutes before you mess with it. There are 3 hooks on the steering wheel base that the airbag hooks onto. On the back of the airbag, there are heavy guage "wire" loops that hook onto the wheel. There are holes through the back of the steering wheel trim (you have to remove the steering column trim first) that you stick a screwdriver through and pry the loop off the hook. You have to turn the wheel as you go to access them all. The clips are really hard to get off the hooks, and it took several tries to get them all worked loose. Once you get it loose, there are 2 electrical connections. Be very careful with them and be sure not to break the clips on the connectors, the guy said if they break you have to buy a new harness because the airbag won't work if they are broken, and you will have a light on your dash all the time.
I had trouble figuring it out, so the guy helped since he said they removed them often. He still had a little trouble, but had it off in a few minutes. He got the airbag out, and I removed the connectors. Sorry I can't help more with the airbag part.......hopefully you can get it figured out.
