For your information, the tail light wire contains 7 pins where the 3rd pin is inactive.

Let’s go deep into the wiring connections of the f250 tail light to the 4-wire trailer connector:

  1. Left turn signal or brake wire to pin-1 (Yellow-color wire).
  2. Right turn signal or brake wire to pin-2 (Green-color wire).
  3. License & park light or tail wire to pin-4 (brown-color wire).
  4. A reverse light wire connects separately on the left and right connectors.
  5. Ground wire to pin-6 (white-color wire).
  6. CHMSL aka center high mounted stop lamp wire to light blue wire.

Ground (Negative) Wire

At the back of the tail light, you’ll see a black wire which connects to the f250 truck ground. And, this wire is the ‘negative’ or ‘ground’ wire.

Even if nearly all f250s tail light’s ground wires are black, some of them can also be black with yellow stripe, green, or orange in shade. This wire is connected to the truck’s and tailer’s ground point.

License & Park Light Wire

Seeing all the wires at the rear side of the tail light might confuse you to determine the license and park light wire which is mostly in brown shade. It is connected to the truck’s wiring harness on f250 and tailer’s taillight.

Reverse Light Wire

Attached to the truck’s backup circuit and backup light of the trailer, the reverse light wire is always pink or black.

In a 4-way, 5-way, or 6-way trailer, this wire is not included. The reverse light is set under the dash in the f250.

Left & Right Turn Signal Wires

Most people get into puzzles to determine the left and right turn signal wires since all of them are being attached together. Now, their color does differ in f250 trucks.

  • The left turn signal or brake wire is light green or orange. And it directly connects to the rear light (left) with a splice and another wire to feed the #1 fuse to illuminate when hitting the blinker switch.
  • The right turn signal or brake wire is orange or light blue. To locate this wire, it will be attached under the truck.

CHMSL Wire

Above the rear window, the CHMSL aka Center High Mount Stop Light wire is mostly green in shade.

It is also known as an extra ‘Hotwire. To find this wire, take out the driver’s side step plate under the hood.
