Connecting a wireless rf receiver to a Arduino board

I’m just wondering how to connect this rf receiver to an Arduino board?

I’m also wondering what wires go into what ports?

Thanks,

DC supply, then two wires…
one to a digital input with INPUT_PULLUP, and common the 0V/ ground to the other relay pin..

I guess it would depend on exactly what you expect to happen? This is where it all begins:

You will be taking a digital pin low much like having a push button (N/O) between a digital input pin and ground. The DI pin held high with internal pullup.

It looks like the receiver relay board has the option of momentary or latching.

Finally I would not power the relay card using the Arduino. I am not sure what the relay receiver board current draw actually is?
