How do I install a HID Kit with a Canbus Ballast?

I have a 2014 honda accord. The bulbs come with a ballasts that has an attached Canbus system connected with two output cables. One looks like I connect it to the Car bulb harness, but the other is a O Ring. Do I ground this cable then connect the other end to the bulb harness? Which in turn is connected directly to the Ballast. The Ballast then has two Mal and female connectors for the HID bulb. Is this correct? And the extra pice of cable with the bulb is not needed.

But if I do need the extra piece of cable. I connect it between the car harness and the Canbus.correct?

Thank you
