DUAL IGNITION TACH ADAPTER (MSD)
MSD Dual Ignition Tach Adapter.
This dual ignition tach adapter is for vehicles using MSD DIS ignition controls. It has 2 channels, for 2 coil pack applications. In some cars, when you add an MSD ignition, the factory ECU no longer can tell when the coil has fired, which is what tells the ECU to fire the injectors or tachometer. This adapter simulates the coil signal, allowing the ECU to trigger both the tach and fuel injection with the MSD DIS ignition. In most cases, the adapter plugs directly into the MSD harness.
For cars using a DIS-4 ignition, 2 adapters are needed.
