How to remove the passenger side air bag?

I figured it out, it is disconnected and out of the vehicle. Now I can continue to move onto removing the heater core assembly.

So far, it looks like I will have to remove the entire dash, got as far as removing all panel instruments & panels and part of the metal skeletal structure on the back side of the face panels. I lowered the steering wheel, but it looks like I may have to remove the steering wheel in order to have enough room to pull out the heater core/A/C plenum. I have replaced a few heater cores in a few different types of vehicles, but this particular vehicle is the toughest and most time consuming, I'm learning and trying to figure out at the same time how to remove this heater core as I go along, I've been on it now Sunday, Monday, Tuesday, and Wednesday. I will be working on it some more today. Hopefully I get the plenum out today. I'm working outside, luckily the weather has been really nice so far. When I get ready to put everything back together it will take even additional time because repairing some plastic pieces that have broken when taking things apart, and a wire repair, and I am usually very careful with working on especially older vehicles not to break older plastic pieces or anything, always take the time and caution so as not to have that extra work in the end but always have to calculate that there will be some problems especially with very old vehicles, just from being old and that other people have worked on it and may have left behind undesirable results for the next guy to work on and that is what I have here but I think this is the original heater core and has not been touched or replaced before. Well, this a real challenge and I'm confident that I will get it done and get it done right. I guess I will spend another 3 days at least to get this done right, including cleaning the ducts replacing old foam rubber tape and other pieces of foam that have deteriorated over time and some repairs.
