Why are the running lights not working on my Toyota?

Where do the brake and turn signals go on a trailer?
You should get left turn and brake signals on the yellow wire, right turn and brake signals on the green wire, and running lights on the brown wire. The white wire is the ground wire. If the vehicle signals are all functioning properly at the trailer connector then you will need to figure out which wires go to the correct circuits on the trailer.

From the diagrams I have, it looks like the tail lights (not brakes or flashers) are tied to the same pin as the marker lights (Pin 2 – Brown Wire).
