sorry for the poor quality image. It's because of defective camera.

Anyway, what that connector called? In case you can't see it properly in image, it's a three pin connector (i am not sure what it is called, so for the time being i am calling it connector). One pin to fed in 'VCC' other for 'GND' and the third pin is to take the output.

It looks like a garden-variety .100" header. You'll find lots in con-amp-quick.lbr. Before using, check the pin spacing and hole size for the square pins.
