These are the gauges I'm starting to refurb on my 350F. Something seems funky to me, because in other pictures of 350f's I'm not seeing the neutral or turn lights in the tach, AND when i turn the headlight on the neutral light comes on in the tach? So is the original style of tach that came with the 72's ? all the wires are there, but this just isn't adding up. I'm begginning to wonder if these are even original. Can anyone shed some light on this?
