I know how to repair odometer and shift indicator display. However none of the gauges including tach and speedo work, Some diagrams would help. Would like pin diagram for instrument cluster plug and possible diagram of printed circuit board, in case something is missing. Car is LS model. Everything else, except radio, seems to work ok. Oh yes, the turn signal indicator and the instrument panel lighting works ok. Currently looking for fuse.
