aftermarket fuel gauge

I have an aftermarket gage in my 1965 Newport (just fuel). I bought it long ago at an auto parts. I recall it was specific for Chrysler (10 ohm full, 70 ohm empty or such). I recall some later ones also supported Ford (0 to 70 ohm?) and GM (90 to 0 ohm?). With today's electronics, they can probably support all 3, or even a modern Chrysler (measured ~1000 to 2000 ohm sender in my 1996 Plymouth), and may even allow calibrating the needle to your fuel tank.

Don't cut any wires. Our cars have been mutilated enough by past gomers. It shouldn't be hard to release the correct pin from the connector in the kick panel. And don't use ugly butt crimps!
