Anderson 4-Way Flat Wishbone Trailer Wire Harness, 25 Foot Split Harness (V5425Y)

The Anderson 4-Way Flat Wishbone Trailer Wire Harness is a 25 foot split wiring harness built to run trailer lighting from the tow vehicle connector down each side of the trailer frame. The harness splits at the trailer tongue into a wishbone configuration, letting each leg run along its own frame rail to the rear lights, which keeps wiring routed cleanly along the trailer structure instead of running a single line down the center. It terminates in a flat four-way plug and includes a trunk connector for tie-in at the rear of the trailer.

Construction uses color-coded, four-conductor wire that meets SAE J1128 specifications, so each circuit (ground, tail/running lights, left turn/brake, right turn/brake) is easy to identify during installation or troubleshooting. The flat four-way plug itself meets SAE J1239 specifications, matching the industry-standard flat connector used on most tow vehicles and trailers. The harness is made in the USA. Because it uses the standard flat four-way plug, it works with virtually any trailer wired for a four-way flat connector, making it a straightforward replacement for a damaged or worn-out factory harness or a build-out harness for a new trailer wiring job.
