Sallysea,

The Ray49's aforementioned pigtail harness is approximately one foot in length. I suspect that the prior owner/installer of your Ray49 VHF radio has lengthened the NMEA 0183 portion of the Ray49's pigtail harness using a length of cable which already had a plug connected to it. While I suspect that the described cable assembly may be that of a a C/E-Series Classic MFD NMEA 0183 Cable Assembly, the only way to be certain about the mapping of how the leads of the added cable assembly have been interfaced Ray49's pigtail harness would be to locate the splice (this would be expected to be located approximately one foot from the Ray49's chassis) and then inspect the splice. Should the added cable assembly added to the Ray49's pigtail harness have been a C/E-Series Classic MFD NMEA 0183 Cable Assembly and should it have been properly wired to the Ray49's pigtail harness, then you need simply splice the C/E-Series Classic MFD NMEA 0183 Cable Assembly to the matching colored NMEA 0183 leads of the a/c/e/eS/gS-Series MFD Power/NMEA 0183/Video Input Cable supplied with your c127 MFD.
