The white wire is typically ground, you can confirm this by checking to see if it connects directly to the trailer frame. Your yellow wire is usually the left turn and brake lamp, green is right turn and brake light. The yellow/black and green/black are running lights, with the green/black running down the passenger side and the yellow/black running down the drivers side. You can confirm this by using a car battery, grounding the white wire to the negative terminal, and applying 12-volts to each circuit, and seeing which lamps light up.

If you are using the # PK11700 7-way connector, and you have tested and confirmed function as described above, your yellow wire connects to the # 5 terminal, the green wire connects to the # 6, and the green/black and yellow/black would both connect to the # 3.
