I hooked up 1 side of the reducer to the gauge power wire and the reducer to the hot terminal on the fuel gauge itself. “IT” I was referring to the harness instructions, they show the fuel gauge grounded. Sorry. With the ignition on there was no reading on either side of the reducer, not even to the gauge power wire. I have checked the fuses and all fuses are good. Yes there is power to the ignition switch, with the ignition turned on. Yes to good clean ground.
