Be aware that you lose the fuse protection that is present on most Nano boards doing this.
Look at the schematic and see what the fuse value and type is and put your own fuse in series with your external supply.

Look at the GPIO connector. The pins are marked on that. Pins 29 and 30.
Be aware that using a long ribbon cable will cause a voltage drop at the T3. You may read 5V at your input but it can be as low as 4.7 at the T3 due to voltage drop and it does not like this. I saw this with an M3 I powered from a 10cm cable. I ended up having to cut this down to max 2cm and use thicker wire to ensure the current drawn did not cause the drop.
Another place to power the board is from the UART debug connector.
As davef said, put a fuse in this line to protect the T3 as powering this way bypasses the protection on the board.
