Didn't notice I'd wired my 6v pickup for negative earth until I saw it showing a charge when cranking, easy to change.
You didn't say what age of Dodge you were working on, some of the really early fuel systems had a two wire fuel gauge system which was basically two circuits in balance, with the guage showing the 'difference' between them in response to the float level. As I understand it even if you got them reversed it just indicated wrongly (full when empty) so I don't think it would be damaged.
