Civic EG

Ok Ive been searching and searching and I've checked my fuses inside my eh hatchback and they are all good and my lights are working, but my gauge cluster isn't working at all. The temp, mph, rpm, and gas don't work at all. The gauge illuminates though. I even switched my guage cluster with another and it still doesn't work. Help please , I'm running out of ideas of what it could be

have you tried checking the the ground for the main power of the gauge? may be its loose. the two sockets at the back are the ones sending signal and the other, the one that illuminates the cluster, try to check its continuity...
