Triton 12221 TC Series Trailer Tongue Wire Harness

The Triton 12221 Tongue Harness is used on TC Series Trailer. It has a 7-way RV style plug on one end (vehicle side) and a 4-flat plug on the other end.

Ask the Triton Expert:

"What is the color code for the wires on my Triton trailer?"

Most trailers have four basic wires for trailer lights. Trailers with brakes will have more for the braking systems that are available. Shown below is the basic coloring for Triton's trailers.

No Brakes-
Yellow= left turn
Green= right turn
Brown= running lights
White= ground


Surge Brakes-
Yellow= left turn
Green= right turn
Brown= running lights
White= ground
Blue/Gray= free backing valve
(goes to vehicle reverse lights)
Normally the center pole of a 7-round plug is for the free backing valve

Electric Brakes-
Yellow= left turn
Green= right turn
Brown= running lights
White= ground
Red=electric brakes
Black= breakaway battery hot wire
Blue= backing lights


Any additional 12v accessories would have to be addressed separately.

Ask the Triton Expert:

"Why do I have more wires than connections going into my plug?"

The front wire harness plugs that plugs into the vehicle may have extra wires running into them. You might notice that you will have 6 wires going into a flat four plug. Most of the time the running light wire (brown) and ground wire (white) is ran to both sides making it look like 6 wires are going into the plug. Your plug basically merges these two "like" wires together to make the standard four wire connection of yellow, green, brown, and white.

If you are splicing in a plug instead of getting a new front leader section then simply merge the two white wires and the two browns wires to go from 6 wires to 4 wires to match the new plug.
