You could have disturbed the connector to the passenger airbag or if you have side airbags moving the seats about may have disturbed the connectors under the seats, a common problem. Otherwise the rotary coupler behind the steering wheel. Diagnostics would pin point the actual problem.
Put your location in your profile, there may be someone nearby with diagnostics who could help.
