Thermostat wiring

[Barten10]

I have 6 wires going to my old thermostat. Five of the wires match the Nest product, however there is a brown wire but no label for it on the board. The only spot left is o/b.

Should I connect the brown wire to that terminal?

Post a picture of the original thermostat's wiring.
