PN 89631
In the past, adding ignition boxes and coils to factory transistorized ignitions was virtually impossible. All that has changed now that MSD has developed the Dual Coil Ignitor and CPC Signal Converter. The MSD PN 6302 and PN 6304 both allow you to install an MSD DIS-2 or DIS-4 on 4-cylinder engines with either waste spark or coil-per-cylinder ignitions. Both require MSD coils to be installed for a complete package.
