Trying to connect a Furuno 7000F plotter to a Furuno 1623 radar. 6 pin to 7 pin, I was told to flip-flop the Yellow and Green and flip-flop the black and white? does this sound right? Any help would be great. thanx in advance. just read an article by Dry Doc? that made perfect sense, I just need to figure out wich wires are talkers and listeners.
