MSD - Designed for current-limiting ignition systems (non-ballast resistor systems) 438 in - 1If you are triggering an MSD 6 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.
