Manufacture Part number: 89121
Note: Two Required. In some instances when you install an MSD Ignition, the factory ECU may not be able to distinguish when the coil fires. This is the signal that is also responsible for firing the injectors (or the tachometer), which may cause a no-run situation.The Dual Channel Ignition Adapter simulates the original coil trigger signal thus allowing the ECU to properly trigger both the tach and fuel injection with the MSD DIS Ignition installed. In most cases, the Adapter plugs directly into the MSD’s Harness. For vehicles using an MSD DIS-2 Ignition, only one PN 8912 is required. For DIS-4 applications, two PN 8912’s are required.
