First yu need to check yur fuses . There is a fuse that is dedicated to powering the Speedometer and Tachometer , it is odd they will both fail at the same time unless the IP itself is bad , the fuse is burned , or sumone had changed the colour of the speedo and tach gauges and removed the needeles etc and it affected the cluster and caused the gauges not to work , or if the Instrument cluster is missing screws holding it in , or the panel is not tight , this can cause the tach and speedo not to work.
The Instrument cluster sits against the socket , the instrument panel plug in is held on a bracket behind the instrument cluster. So the cluster is just installed and pressend against the socket and held there with the screws. If scres are missing or the cluster is not pushed all the way in against the plug in , it will effect operation of the gauges
