ArmyChevy is most likely referring to a 1958 Chevrolet truck, that has a foot-start switch/box that provides the 12v "shot" bypassing the ballast resistor. Just in case 6v people are wondering about the side-post in Bill's photo, that is for 12v installations (the 6v foot-start switch/box does not have or need that side post).
