Headlights and dash gauges weirdness
When I turn on my headlights, my gas gauge and temp gauge move to the right. The amp gauge is not working and oil pressure gauge is not even wired. I would assume they would act erratically as well but let’s go with what we have.
Since both gauges are doing this, I think the problem would be some sort of ground problem with the light switch but I’m no electrician. Has anyone here had the same problem?

I would suspect a short of some sort on the printed circuit on the back of the cluster. Power from the dash light circuit is somehow bleeding over to the gas & temp gauges. Amp gauge is on a completely different circuit from the others. That's my best guess.

Is yours doing that while it's running?

When you remove the cluster, it's behind that. There's a body-color triangular brace which supports the column, and there should be a black wire screwed to that brace. I believe that the wire comes out of the harness which plugs into the cluster. The wire should be black.
