If you are triggering an MSD blaster, 5, 6, SCI, or 7 series ignition with its white wire or points terminal, you will need the PN 8910 tach adapter. The PN 8910 will correct the operation of most voltage-triggered tachometers or fuel injection systems that do not work directly off the tach output terminal of the MSD ignition unit.
