Default Service Air Bag Light-- Location of decoder plug-in

I recently started receiving the Service Air Bag light. I have a decoder provided by the shop that tuned my 2005 CTS-V on a dyno. I went to plug in the decoder to read the code, only to realize I can't find where to plug it in!!!

Two questions-- where do I plug in to read the fault code,; and 2) Any suggestions on the Air Bag problem and the fix? The car is well maintained with 95K miles on it.

OBD port over the driver's feet. Only some scan tools read SRS and ABS codes. Never had an issue with my V, but on most SRS systems the likely culprits are the passenger occupancy sensor (was a recall) or the clockspring.

Passenger presence sensor, or if the seat belt pretension system has been activated or failed it will cause the same message.

You need a tech 2 or similar device to read the airbag codes .

You need a code reader that can read CAN bus. Otherwise all you will see will be engine codes.
