2005 ford five hundred passenger air bag light?

-my five hundo had an issue with the seat belt chime going off when the seat belts were buckled so i clipped the wires on both belts to stop this from happening.
- now i have to get it inspected and the airbag light is on. How can i fix this issue? The mechanic is stating they need to replace both seat belts and a sensor on the seat which will cost 1600 bucks! Is there any way to bypass this sensor and connect or disconnect wires to turn the light off?

Repair the damage that you caused by clipping the wires on both belts
