This one may be too big. You need to measure the space first. **Q: What is the connector? i bought this and the jst connector does not fit the jst connectors i have, so what is that connector ???** A: It is JST PH (2mm pitch). There is 12 types of JST connectors listed on Wiki. **Q: Can i cut the connection off so i can solder it to a circuit? if so which do i cut first?** A: Cut one connection at a time, do NOT cut through both at the same time… if you short them together they may weld together and then proceed to burn.
