DC CDI: on most scooter is a 4 wire set-up but has been known a 5 wire set-up also, the sure way to know is to check its power source. Mechanics Note on distinguishing AC fired or DC fired CDI box Wire and Plug In the GY6 6-plug set-up, you have AC if you have 3-wires going into the 4-plug side and you have 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. AC And DC Size In general, the DC CDI's tend to be larger in size than the AC ones. Headlights if the headlights turn on without the engine running, (with just the key on), it is a DC system. In the AC system the headlight requires the engine to be running. Another indication is, if the engine will only run with a battery it is DC. If it will run without a battery, it is a AC system. ## Features - 2 Plugs wiht 6 Pins, for GY6 Engine NYCSP0007/ No Rev Limit Tuning ECU - DC Fired, Square Plug/ Type: Motorcycle Igniter/ Big Size DC CDI Fit 125cc 200cc 250cc Atv Dirt Bike - This CDI Eliminates Rev-limit that Keeps your Bike Restricted and Reset the Ignition, Advance Curve for Better Acceleration - Note: One Wire at the CDI Plug need DC CDI.
