If you google RS 232 pinout, you'll get the information you need. You might want to learn how to use google, since it can answer a lot of the basic technical questions, like what are the RS-232 pinouts.
BTW, the pinouts are 2 is Receive Data and 3 is Transmit Data, and 5 is signal ground. If you connect the NMEA OUT + to Pin 2 and NMEA IN + to Pin 3 and the NMEA OUT - and NMEA IN - wires to Pin 5, you should be good to go.
However, not all NMEA 0183 ports are RS-232 compatible... some are RS-422 ports, and some of the pickier RS-232 to USB dongles won't want to play nice with them, because they won't recognize the change in signal levels. IIRC, RS-232 is an unbalanced protocol, and RS-422 is a balanced one, with lower voltage signal levels.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
