I just purchased this Grove RTC. It includes a cable presumably to connect it to a breadboard and/or Arduino, but the pin holes on this cable are much smaller than those on a breadboard or Arduino.

How/where would I connect this in the case of using an Arduino Uno?

    If you want a quick temporary solution, you can probably stick 22 gauge wires in that connector, secure with electrical tape and put the other end in your breadboard. Commented Mar 19, 2016 at 21:04

    I would get two jumper wires (with a male plug at each end) chop them into half so you now have four wires, each with a bare end and a plug, strip the wire where it was cut, and solder the 4 bare wires to your socket, and then plug the plugs into the breadboard.

Either use jumper wire, or pull the connectors from the Housing and connect them with male connectors.
