RX TX connection with m365 board

Apparently I solved my issues with software, but one point regarding hardware is not clear for me.

There is a note:

The only extra wires going from the BMS to the M365 are RX and TX!

Between m365 and oryginal BMS it plug with 3 wires (green, yelow and white). Which wires are RX and TX? Which should be connected to new BMS?
