That cable can be a hassle to work with, maybe try to find a breakout board that would work with it. But anyway, you need to connect the devices GND, RX and TX pins to the Pis serial TX/RX pins. Your device seems to be powered by 3.3V so they should be level compatible. And looks like you also need to connect the nTrig pin to a any suitable GPIO pin to be able to trigger a reading.
