No dash gauges for a 92 Nissan Pulsar

If you have power to the gauges, it has to be a bad ground or it could be something wrong with the gauge cluster.
Pull the speedo head on the back of the speedo is a small box plugged into it call nissan or hit up a salvage yard. It is available after market, but...not japanese.
Dodge called it a surge protector. Dont know what nissan calls it I had one if these once,and that was what was wrong w mine
