Maybe I don't understand the question, but: The only colors that matter are the brown (tan) and light green wires from the truck harness.

The brown (tan) wire from the truck is the low beams and should go to the low beam relay coil. The wire from the relay switch goes to the horizontal tab on the bulb connector.

The light green wire from the truck goes to the high beam relay coil. The wire from that relay switch goes to the vertical tab on the bulb connector according to the diagram in the post.

Then hook up the grounds, and power wires.

Good luck men,
