Red and black are power and ground, blue and white are gps output signal connect those to 9 pin connector pins 2 and 5 and get a 9 pin(serial) cable to usb adapter for input to a laptop, charting or mapping program and you are good to go. just make sure if you are using xp to wait until the mapping program is running and searching for gps signal before you connect the serial or usb because windows thinks the signal is from a mouse and the cursor will turn into a raging crackhead jumping all over the screen and randomly clicking on whatever it touches.
