Many use a 1 k, 1/4 watt resistor in series with one lead.
If you are sure the loco has LED's already, the resistor is probably on the PC board in the loco. I am not familiar with the Athearn DCC setups. Most factory equipped DCC locos have the resistor on the PC board.

Below is a link about using LED's.
