Where is the location of the Airbag Control Module and how long to change? on 2000 Jeep Grand Cherokee

I just purchased this Jeep with the Airbag light on? I ordered a used Airbag Control Module to install. If that doesn't work, what else is recommended. I am having doubts that it is the CLock Spring, cause my horn and cruise works fine. Any advice please?

I had this fix on mine for about $320.00 at Merchants Tire and Auto. It has to do with the drivers side seat and it runs thru the vent on the drivers side from what I could see how they fixed it for the least money. Hope this helps.
