Ignition Coils
Each ignition system uses a different oil-filled ignition coil. The wire terminals are designed so that the interchange of the 2 types of coils is not possible. The "DEC" (negative) coil terminal connects with Green wire of electronic control module. The "BAT" (positive) coil terminal connects with Red wire (Yellow wire on AMC) to the electronic control module and the ignition switch, through the ballast resistor on Dura-Spark II and Solid State ignition systems.
