I replace my heater core and I am guessing I must have disconnected something for the airbag. Checked the wiring diagram and I am going to trace all the lines tonight, but offhand does anyone know of any connectors for the airbag that would be under the dash that I would have disconnected to remove the heater core? It will be a starting point at least.

 

maybe the fuse blew.

 

Found it. 4 pin square connector under the hood by the AC accumulator was disconnected.

 

glad ya found it
