The only shunt wire I have had in hands, was barelly 3 or 4 inches, from a 75/76 Coronet
I actually pulled the harness apart on one and changed the lenth as I made it a little shorter so the gauge would show more as it never moved before. I would say it was 2 to 3 feet long. But I also worked at a Ford dealer for 8 years before I did 24 years at a Dodge dealer and it may have been a Ford as I dont remember which car it was but Ford also use a shunt type ammeter on some of its cars as it was an option.
