I've got one, and while I haven't hooked it up permanently, I have done research and testing on what would be needed.
The two black wires are ground, one is the shield and the other signal/power ground.
The red wire is power. Some of these are 5V, it looks like the one you got is 12V. You power the unit by putting 12V between the red and the black.
Green is TXD (the one you'll get NMEA Strings on)
Yellow is RXD (If you need to communicate with the unit)
You receive or transmit data by using the black as a reference and going to TXD or RXD.
You'll need a signal level converter to make this work, either to USB or to GPIO. When I originally tested mine, I used an RS232-USB cable. The small issue was that I had to break out the red and black wires to power the unit externally. Unfortunately, you won't be able to connect this directly to GPIO, but RS232 to TTL (3.3v) converters are available if you want to do some circuit wiring.
If you decide to use GPIO, you are going to need to either connect to one of the UART pins or use something like SoftSerial.
