Review on Nilight TR 04 Tailgate Sequential Lights，2 by Eric Montgomery

For Toyota Tundra 2026 the plug and play connection is useless as the brown wire (which is the daytime running light wire) will not work if you connect the 4 pin connector directly to the wire harness. Instead, you can connect the brown/headlamp wire to the green wire on the back of the taillight and the return wire to the positive return wire on the taillight. The white, green and yellow wires can be connected to the corresponding wire of the tow cable behind the bumper, eventually cutting and discarding the 4 pin connector from the light bar.
