Im kind of going through the same thing with my sons Tacoma we bought this weekend. The air bag light is on. Frickin air bags everywhere. Then the bench seat is bad ( broken springs) and He wants a set of bucket seats. So tonight I walk across the street. The neighbor has a Sienna, and a Corolla. Looks like the Corolla would fit good with some custom brackets. Thing is, IDK if I can just plug in the seat side air bags and be OK with that. Worse case, the air bag light will just stay on. They do make some simulators that you can plug into the wiring that will act like an air bag, giving the BCM the signal its looking for. These things are also helpful in finding where the issue is. If the air bag light goes out after plugging in the simulator into the connector, then you know that air bag, or it wiring is the issue.
