Description
Tach Adapter, Blaster 5/6/7/SCI Series Ignition Systems, Each
If you are triggering an MSD Blaster, 5, 6, SCI, or 7 Series ignition with its white wire or points terminal, with a non-current limiting ignition (originally equipped with a ballast resistor) you will need one of these MSD factory ignition module tachometer adapters. They correct the operation of most voltage-triggered tachometers or fuel injection systems that do not work directly off of the tach output terminal of the MSD ignition unit.
