Suit MSD Blaster, 5, 6, SCI or 7 Series Ignition
- For use on non-current limiting ignitions, originally equipped with a ballast resistor.
After installing an MSD Ignition Control, if, your tachometer, fuel pump relay or electronic fuel injection doesn't operate correctly, your application may require a Tach Adapter. This is due to the trigger signal not being strong enough to trigger both the MSD and the factory's components.
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 MSD8910 Tach Adapter. This adapter 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.
