Custom Wiring Harness 56256

This Curt Manufacturing wiring harness is a custom-fit electrical connector designed for trailer, plow and towing equipment. It provides a direct interface between a vehicle’s lighting system and a trailer plug without splicing. The component is new and intended for owners who need a reliable, vehicle-specific connection for towing duties.

Upgrades from universal adapters

The harness replaces generic splice-in kits that require cutting factory wires and adding separate connectors. Because it is built to a single application, installation is faster and the electrical path is shorter, reducing resistance points. The jump is worth it when the vehicle is used regularly for towing and the owner wants a plug-and-play solution that preserves the original wiring integrity.

Sustained towing performance

Under continuous load from trailer lighting circuits the harness maintains stable voltage delivery across all pins. The moulded construction resists moisture and vibration that can degrade crimped connections over time. California Proposition 65 notices indicate the product contains chemicals known to the state to cause cancer and reproductive harm, so installers should follow standard handling precautions during extended service.
