Overview

The CURT 56427 is a custom 4-flat wiring harness designed for select Cadillac XT4, Lyriq, Chevrolet Blazer EV, Equinox EV, and Honda Prologue models. It provides a 4-way flat output to connect your trailer's tail lights, brake lights, and turn signals. This wiring harness features a simple plug-and-play design that connects directly into your vehicle's existing OEM socket, eliminating the need for cutting or splicing wires. A dust cover is included to protect the connector when not in use.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
