speedo and tach not working

Hello everyone.
My speedometer, Tachometer, and all of the lower info gauges are not functioning at all. The temp and fuel gauges are fine. any and all info would be greatly appreciated. 1997 boxster. Also I checked all fuses and have tried to find if a relay is the culprit, but no luck.

Is it possible that one of the connectors has come loose? Here's a link to an article that includes instructions on how to remove and reseat the connectors: Porsche Boxster 996 Gauge Cluster Upgrade - 986 / 987 (1997-08) - Pelican Parts Technical Article

Under the gauge cluster there are 3 large connectors...white, green and blue. They have poor latching devices that could have been partly undone for years and just popped off. It's not too hard getting in there but if you get stuck I could dig for a while to see if there is anything here you can use. I had to replace my entire dashboard and when reassembling this one of the connectors was a pain in the ass and I had to go back in to reconnect it. I can't say which one...it's been a few years.

gauges not working

Thanks so much for your reply. I did as you suggested and pulled the cluster (surprisingly easy) checked the connections, and all were tight. I re-checked all fuses to no avail. Is there
some relay that I am missing? Again only tach, speedo, and lower info lights Mileage ect. are not working at all. The needles on the speedo and tach don't even quiver. Thanks again for your input

Check every fuse

With an Ohmmeter or continuity lights, pull each one and move on...then make sure the connectors are seated all the way in the Instrument CLuster
