Colors may vary but this should be the map for Raspberry UART0:
Pypilot tx -> RPi rx (GPIO15, pin 10)
Pypilot rx -> RPi tx (GPIO14, pin 8)
Pypilot GND -> RPi GND (any pin marked as GND)
Pypilot Vcc -> RPi 3.3V (pin 1 or pin 17)
Maybe you could use a GPIO header extender to get longer pins. A workaround could be to use the Rj45 connector because it is directly connected to UART0, but ATTENTION, there is 12V there, you need to connect only UART0 tx and rx cables and take GND and 3.3V from the 1-wire connector. Ugly, but it will work until we find a solution.
Oooh I like the rj45 connector idea as I am not planning to use the Maiana AIS system. Is there a pinout diagram of what is what on that? I can probably find 12v with my multimeter (to avoid) but any help on which other wires I would be connecting would be helpful! If I assume a t568b RJ45 end ?
Thanks!
