Gauges 1966 temp/gas part missing
Does your dash look like this (minus the red wires and digital regulator!). My gas and temp gauges were not working, so I cut out the original mechanical voltage regulator in the gas gauge and installed this digital regulator. A FABO member was kind enough to help me through it. Gauges work now, but the gas is off by about 1/4 tank. When it indicates empty, I still have a 1/4, so I'm good with it (probably the junk aftermarket sending unit). I didn't have any black wire and didn't want to buy any so I used red for everything!! It's been working for a couple of years now.
Oh, and like RedFish pointed out, grounds are critical. I ran one from each circuit board to chassis ground.
