Airbag Sensor

I am working on my brother's 96 cav. It was in an accident and the Airbags deployed. He purchased an airbag set that included a sensor, but I cannot find where it goes. I am going to try to attach an image of the sensor. The one in question is the large sensor in the middle underneath the stearing wheel cover. Please Help.
