ā€˜66 Barracuda Fuel Gauge Pegged!

The upper harness shows no continuity with ground, reads ā€œIā€.
My bench test was with 12v to the IVR, with the Chinese sender, was working like it should. Prior to that, I tested only the fuel gauge with three 1.5 AAA batteries from a flashlight and the gauge would move up and down.
