On the Norcold N20DC (and N15DC), that plug at the bottom of the right refrigerator door connects the door's electronics to the fridge. The right door holds the control panel / touch display and the door handle LED. Their wiring runs down inside the door and exits at the bottom, near the middle hinge, where it plugs into a mating connector on the cabinet under the bottom wire cover.
If you removed the door to move it, swap the hinge side or replace it, reconnect that plug before reinstalling the door. Otherwise the display and the handle light won't work. If the display is dead with the plug firmly connected, check the pins for corrosion or pins pushed back into the housing. The cabinet-side connector is part of the main harness, so it isn't sold separately. Related N20DC parts: Norcold Door Bin 641064 / 50981 (fits N20DC) and the Norcold Control Board 641043 (N15DC/N20DC).
