The cable that came with the GPS had a male 8 pin connector at each end, so I decided that if I simply cut the cable in half, I could make two new cables: one with breadboard compatible pins and another that could later be soldered to whatever circuit board I planned to make my GPS project on. The cable shown in Figure 14 was cut in half and then one side was separated so that each wire could be soldered to a breadboard compatible header pin. Since SparkFun also sold these small cables and sockets separately, I could always acquire another one if I decided to use the original socket on a printed circuit board later on.

Once the eight colored wires were soldered to the header pins, the GPS cable was now ready to be plugged into any solderless breadboard for rapid prototyping. The colors of each wire were fairly obvious, with red being VCC and black being GND, so it would be difficult to connect the power in reverse. Besides power and ground, the only other wire I planned to use form the possible eight, was the serial transmit line (white wire). I connected all eight wires to the header pins just in case I wanted to experiment with changing the default parameters on the GPS module using the serial receive line. Figure 15 shows the completed breadboard compatible GPS module and cable.
