    The alarm is screwed in the back of the main instrument cluster. You pop off the trim bezel around the cluster, then remove 4 screws that hold the cluster in. Once you disconnect and remove and cluster you remove the metal back plate. There are about 12 screws or so that hold this on. The alarm/beeper is screwed in at the lower right side. Usually connected to the main board by only a red and black wire. It depends on the year, but some beepers have a connector to the main board, and others just have the wires soldered. Easy to replace either way.
