The fan connector has two pins with +5V and two pins with GND.  You can use a "Molex 43025-0408":https://octopart.com/43025-0408-molex-24935555 part to mate it.  This is just the housing, you will need crimp contacts and matching crimp tool, or you use pre-crimped wires like "Molex 79758-0010":https://octopart.com/79758-0010-molex-24727080.

On the back (connector) side, in one corner there is a black rubber cap over some kind of high density debug connector.  You have to remove that rubber cap completely (not just the connector part) and will notice a pushbutton underneath the location where the rubber lid is fixed to the enclosure.
