Just a heads up, there is also a safing sensor in the B pillar driver side.
Excerpt from http://www.veryuseful.com/mustang/tech/airBag/airBag92.html:
The primary sensors measure the crash severity while the safing sensor confirms the crash and is used to prevent inadvertent deployments possibly caused by a malfunction in the primary crash sensor circuits or crash sensors.
