Airbag impact sensor location, 03 QX4

[Mike W.]

While visually good, it's become apparent my 03 QX4 had been in some sort of a shunt before my ownership. A repaired headlight housing, lack of any sort of metal front bumper underneath the plastic, although one good and one very bent up bracket are still present, and missing grill pieces. Not what I'd like, but I could have been born rich and good looking and I'm over that too. But more to the point is where is the airbag impact sensor located? I'm wondering if it might be missing, or even just hanging loose, although there is no sign of airbag deployment, but it's no longer a new car. No warning lights either.
