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!!
