Hey guys….new user name….my old user name wouldn’t work after multiple attempts…ANYWAY…. Lol I’m operating/managing a 2011 Azimut 70 and am trying to connect a NMEA black water gauge to the current sending unit. The sending unit has 7 wires compared to the NMEA cables 5. After much searching online, I can’t find which ones I need to connect. bTW- we are bypassing the Azimut master panel. The owner just wants a gauge that he can look at. Judging by the looks of the junction box at the tank….I’m Not the first that has been messing around in here! Thanks! Rob
