I was going to mention look into the shorting bar. You said you were in there a bunch that's the most common fail point. I can't remember if the shorting bar is on the airbag or the wire side but logically on the airbag side.

About every other year that issue comes up on xoutpost and a shim made with a piece of old cc usually all it takes to fix.
