You have AC if you have 3-wires going into the 4-plug side and 2-wires going into the 2-plug side. On the other hand, you have DC if you have the larger CDI box, 3 or 4 wires going into the 4-plug side and only 1-wire going into the 2-plug side. 2. If headlights turn on without the engine running(with just the key on), it is a DC system. In the AC system, turning headlights on require the engine to be running. Another indication is, if the engine will only runs with a battery it is DC. If it will runs without a battery, it is a AC system. Please check whether you need the AC fired CDI or DC fired CDI for your scooter before you order it ,thanks. Package Includes : 1 x Ignition Coil 1 x AC CDI Box (6-pin) 1 x Spark Plug (A7TC)
