Toook a while to get to it but found that the aluminum solid wide from the trunk to the fuse box was the problem. I cleaned up the connection for the guage and that helped but once in a while it would mess up and then stopped working this week. The gauge was pegged at past full so that means it's not getting a signal. I found a store with 18 gauge pink wire put a new wire from the gauge to the pink wire in the trunk on the side of the connector where is has copper strand wire and the gauge is working properly now. That does it with the aluminum wire which will be replaced this winder with new copper wire. I have to find the clips for the connectors so if someone has a source for those please let me know...🙂
Sorry for the stupid question - what's the deal with the AL wiring? I thought that all of the gbody wiring was CU? In my mind, AL wiring stinks. I can remember back some time ago hearing about all kinds of issues with Al wiring in the homes in my area. Issues cause from oxidation, I think.. Glad that you found/fixed your issue - always cool and satisfying to fix an issue you are hunting for.
