I should also add when I say “everything is working” that is without the gauge cluster attached. None of my gauges or warning lights work, which could very well be connected to this problem.
I want to find this short first, then focus on the gauge cluster second.
The instrument panel doesn't have a ground wire. so, while it dangles from its harness connectors, the only features that will function are brake warning lamp and oil warning lamp. Those get their ground at remote switches.
