Hello,

If you would please upload a picture of the harness that you have purchased. This will allow me to see the orientation for each color of wires. That can help me determine which colors you will have to attach.

One thing I can tell you is that the brown wire from the factory harness goes to the center wire of the connector.

I have attached the wiring schematics that show the color and position for the wires.

Please let me know if you have any questions.
Thank you.

From what I can tell from the picture, it should be blue with black, yellow with red and brown with green.
