Wesbar 4-Way Flat 25 FT. Trailer End - Wishbone Harness - 3 FT. Ground

The Wesbar 4-Way Flat 25 FT. Trailer End – Wishbone Harness – 3 FT. Ground is an essential component for any reliable trailer electrical system, suitable for towing utility trailers, boats, or enclosed cargo rigs. This connector assembly is designed to effectively transmit brake, turn signal, and running light signals from your tow vehicle to your trailer, ensuring optimal performance without voltage drop or signal loss.

Constructed for durability in harsh roadside environments, the wishbone harness design minimizes corrosion exposure and ensures consistent contact, which are critical factors for safety and compliance with DOT lighting standards. The 4-way flat connector is the industry standard for light-duty and medium-duty trailers, accommodating ground, left turn, right turn, and brake/tail light circuits in a compact, weatherproof package.

With a generous 25-foot harness length, this product provides ample reach from the vehicle connector to trailer-mounted junction boxes. The integrated 3-foot ground wire ensures proper earth reference, eliminating potential grounding faults that can lead to intermittent lighting issues. This harness is compatible with any standard 4-way flat receptacle on your tow vehicle and pairs seamlessly with matching 4-way flat plugs on trailers.
