yes but it was the bad sensor (I just wanted to check if it was a connection issue as it looked good visually)...
the new/used GM sensor arrived yesterday and I replaced it after wiping it down and giving the pis a shot of deoxIT D5 cleaner preservative...reattached the battery and started the Denali...no air bag light and no air bag error message.
I then ran another BlueDriver scan (after removing the in memory air bag fail message) and got a clean bill of health for the air bags...
this is a pic of the original one...the newer/replacement one looked like it had a 2010 manufacture date if I read the "clock" embossed into it...
