Running lights on my trailer

[Joe3125]

Hi ya'all, I'm thinking about adding one or two running lights on the sides of my trailer (replacing the reflectors). My question is, would anyone know which wire is the taillights wire. Im using the 4 prong connection if that helps. My guess would be that its the Brown wire since its the same on both sides but wanted to double check.

Thanks in advance.
