Micro Servo wires
Jeremy & Havelock
JST connectors come in many different sizes and I use them when connecting electronic boards together with wires, using the plugs and sockets. The pins and pitch vary greatly and I'm not sure that the suggested plug will fit. The design is for a self locking plug and socket that keeps the connection solid.
Not sure if you have a servo plug with wires attached. They are available and an extension lead can be cut in half. With a standard servo lead the easiest solution would be to cut off the JST connector, part the three wires then sleeve and solder to the wires attached to the servo plug, brown (to black), red to (red) and orange (to white). The servo wires appear to be similar to the standard Hitec colours.
