Black/Brown |
Red |
Orange/White/Yellow/Blue |

While it is usually possible to power the servos directly from the Raspberry Pi 5V pins on the GPIO header, they can draw a significant amount of current when moving. Unless you have a very good power supply, this can cause the Raspberry Pi to reset unexpectedly, risking corrupting the SD card. Therefore, it is recommended that you power them separately; for example, with an additional USB power supply and cable connected to the ground and positive supply.
By default, the servos can be wired as follows:
