Description
xWhen towing with your Toyota Tacoma, reliable trailer lighting is essential for safety and visibility. The Nilight 56349 4-Pin Trailer Wiring Harness Kit is designed to integrate with 2016–2023 Tacomas, using OEM-compatible connectors that plug into the vehicle's wiring behind the taillight housings. With this setup, your trailer's tail lights, brake signals, and turn indicators can share a single, consistent connection without the need to modify factory wires.
Designed for straightforward, cut-free installation, the kit avoids permanent changes to your vehicle's wiring. The plug-and-play design means you can connect the harness to your factory wiring and access a standard 4-way flat trailer connector located beneath the rear of the vehicle after installation. The rugged dust cover keeps the 4-pole connector protected when not in use, helping to extend the life of the harness in variable weather conditions.
Vehicle-specific compatibility
This harness is engineered for Toyota Tacomas from model year 2016 through 2023. The OEM-compatible connectors plug directly into the factory wiring behind each taillight housing, providing a clean, reversible upgrade for trailer towing.

With the 4-pin output in place, you’ll have a ready-to-use trailer lighting system that integrates with your Tacoma without permanent wiring changes.
In daily use, the Nilight harness could help keep trailer lighting signals in sync on highway trips, campsite runs, and DIY hauling tasks. The compact, plug-and-play design also makes it easy to remove or reconfigure if you upgrade trailers or hitch setups in the future.
