It looks like you have a standard 4-way trailer wiring harness therefore the white wire is indeed a ground, the brown wire is for the running lights, the green wire is for the right side stop/turn signal lights, and the yellow wire is for the left side stop/turn signal lights. If you are having issues with the right side stop/turn signal lights then first check to make sure there is not a fuse blown in the tow vehicle but if not then you need to start tracing the green wire all the way back to the tail light. If no breaks are found then reground the light and then check the bulb.

I have attached a list of our trailer wiring harnesses for you to look through as well as a trailer wiring help article.
