Made a header board so I can leave the standard plugs on my servos and just plug them into this which plugs into my arduino.
This allows me to leave the original plugs intact in case I need to replace a servo or use it somewhere else.
Header pins match up to the input pins on my arduino and are jumpered to rails which link up to other header pins on the other side bent at 90 degrees to allow my servo plugs to plug right in.
