I would recommend using a circuit tester like part # PTW2993 and test the the pin on the trailer connector that corresponds to the brown wire.

I would recommend confirming that you definitely have the tow package, as part # 118339 will not work on vehicles without the OEM tow package. If this part is used on a Frontier without the tow package, the running light circuit will not work without adding a relay available from the dealer.

Part # 33525 is designed for vehicles that are not equipped with the tow package.
