okay, there are 3 prongs on the gauge; sender, ignition and ground, what wires do I switch? The instruction clearly state; swapping wires will not solve the problem.
Saw that, but they also claim it will work with any sender or you can do a custom calibration As I mentioned they are not the company they once were. out of curiosity did you try # 6 on the list ?
One could try swapping the 12V source and gauge ground but if they say that won't work ask the [censored] will ???
