This diagram illustrates how the PN 7531 is wired up to an MSD 8.
This diagram illustrates the pull up resistor used in the 7531 to MSD 8.
This diagram illustrates how the 7531 rev-limiting functions are wired into the MSD 8 engine saver PN 8978.
This illustrates what changes need to be made in the 7531 data editor screen when using a 7531 to an MSD 8, 10, or promag.
This diagram illustrates how the 7531 is wired into the new MSD 8 plus. The original MSD 8 didn't have a points input.
