If you do anything with any airbag components, first, disconnect battery
when done, make sure everything it back to original connections BEFORE you reconnect the battery. That "should" prevent an airbag light from triggering.
As for the lights, if the CHMSL works I would assume that the brake switch works. I would check the actual bulbs, make sure they are correct and work with a test wire, and check socket wiring.
