These are a bit different. Pull the dome lamp switch out, check for power. If you have it, bridge the wires and if the lamp comes on, you've got a bad switch. If you have no power there is a relay that powers the seatbelt warning system and the l/f door switch. Its behind the cluster and really is no fun to replace.
