Instrument Cluster ground issues? possibly?
 

I am looking for anyone who can provide me with the pinout of the instrument cluster. I am having issues with my gauges pegging both high and low and will jump around randomly. I have already checked and cleaned the ground buss under the carpet on driver and passenger floorboards. I am going crazy trying to figure this out so I can have ACCURATE boost/oil/temp readings. My tach and speedometer are fine. The information LCD will reset but it is still functional. I am at a loss. Thanks for the help!!

i had the same problem on my 94 ssei and i pulled the cluster and found the connector wasnt getting a good connection so i found a salvage yard bought a plug replaced the old one now it works fine
