Intellitronix Fuel Gauge Reverse

There should be a calibration for different years of mopar. The book that it came with does it have a calibration? Usually on the unit there's two itty bitty switches either put them both up both down or one up and one down depending on the setting. I have a universal one that does Ford Chevy and Mopar and I worked on a Ford only one that had four different settings for Ford...
