Will neutral light still work?

Will speedometer need to be recalibrated?
It depends on which machine it is that you're working on. Often however, it does require a different type of neutral switch (usually a single-post switch) to function correctly on account of the revised shift drum's shape. And yes, the speedometer will need to be adjusted. Assuming it's fed by an electronic input, a Dakota Digital Electronic Speedo Adjust Tool would be needed to have your instrument to read correctly.
