Used Wire Harness (Tail Lamp) 1990–2022

The tail lamp wire harness runs from the body electrical system out to the tail light assemblies, carrying circuits for brake lights, turn signals, reverse lights, running lights, and license plate lights. On trucks and SUVs with trailer hitches, it also feeds the trailer connector. Water intrusion into the tail light housing is a very common causes of connector corrosion on this harness. Redline has 18 used tail lamp wire harnesses from 6 sellers. Rear harnesses for vehicles from Chevrolet, Toyota, Mazda, Honda, Land Rover are commonly available through salvage sources, and a full harness replacement is the right approach when corrosion or rodent damage has compromised multiple circuits at once. Brake light or turn signal failures on one or both sides, a license plate light that won't illuminate, reverse lights that stay on or never come on, and failed trailer connector pins that test fine at the fuse box all point to the rear harness. Chasing individual wires in a corroded bundle wastes time. Search Redline by year, make, and model and note whether your vehicle has a trunk, hatchback, or bed configuration since harness routing differs between body styles. Confirm whether the listing includes the trailer connector pigtail if your vehicle is equipped with a hitch.
