What is your tow vehicle? Have they ever worked? Are they incandescent or LED? The yellow is the left, green is the right and brown is for the running lights, white is the ground.
You should start by verifying that the plug is working at the tow vehicle. This can be done by using a volt/ohm meter, a test light or a test plug with LEDs.
If everything checks out, then you need to trace the wires looking for breaks. One of the things I do is use a straight pin, stick into the conductor and check for voltage with a volt meter. Then seal the pin hole with fingernail polish. If you look you will find it.
Good luck, and I am sure there will be advise contrary to mine.
