After completing the winterization of our boat, we took our A50 Raymarine Chartplotter home for the winter. One of my winter projects i to install more Waypoints at my desk. The PWR/NMEA plug connector is not available since our vessel is many hours away.
Can someone tell me which of the 2 large pins for the chartplotter power receptacle is "+12 volts"? (top or bottom) The PWR/NMEA cable part # R62157
When looking at the back of the chartplotter, the two large pins are vertically aligned but favor the right side of the socket.

Many thanks!
