If you can't easily find the glitch in the harness itself, I would just cut the wires, tape off the sides going to the harness, and then run a clean feed from one of the gauge bulb feeds that works properly, along with a nice clean ground feed. Remember, a hot side feed to a filament bulb will show continuity to ground (through the filament) when there is no 12v+ on it.
