    MSD Ignition 89631 - MSD Shift Lights Details

  • Can be installed on 1-12 cylinder engines with stock ignitions or high-powered aftermarket systems.
  • Universal - Works on just about any engine
  • (6) bright LEDs are easy to view in daylight and can be dimmed at night.
  • Programs in 10 rpm increments
  • Supplied with a GMR pickup

    Note: The GMR is a little device that simply attaches, no slicing or cutting, to a current carrying wire and turns that information into a 12-volt rpm signal. It makes installation even easier on diesels, points, coil-on-plug and most any other applications.
