Here's how to use a crimping tool to make your own servo connections. This can be useful to get an exact fit, and also saves you from having to keep around lots of servo wires or wait for servo wires of a particular length to be shipped.
Note that there are two kinds of servo connections: "JR" (also known as "Universal"), and "Futaba". As the name suggests, JR is the most common type.
Note also that this is an area where people mess up the gender terminology. Follow the metal, and not the plastic covers. The large square plastic cover (which looks like it might be the female) actually holds the three male connectors.
