Well my gas gauge stopped working, i checked the harnes the plugs into the back of it and it has power going to it a pink wire, but the brown wire has no power, is the brown one a ground or is it supposed to be from the fuel sending unit? i'm not sure, if the whole gauge cluster is grounded together or what. I checked to see if i was getting power from my sending unit and i didn't is this an easy fix or do i have to get a whole new one and replace it?? i checked the fuses and they are fine. not sure exactly how to fix this one!!!
