I searched this forum and found that the A model cdi has a 6 point and 4 point connector with 4 active points on 6 point plug and 4 active points on 4 point plug. whereas the C model cdi has 5 active point on the 6 point connector and 4 active point on 4 point connector. But the C model shows only 3 active points on the 4 pin connector. Anyone would like to rectify me ???
