Wiring a trailer doesn’t have to mean cutting into factory wires. The Hopkins Plug-In Simple Vehicle Wiring Harness connects directly to existing plugs, giving you a 4-pole flat trailer connector without any splicing. It’s designed as a direct fit solution that keeps things clean and simple.
This harness tucks neatly behind trim and panels, keeping wiring out of sight for a factory-style finish. The hidden design means fewer exposed wires around the hitch area and a cleaner look once it’s installed.
The included 4-flat connector covers the essentials — running lights, turn signals, and brake lights. It’s the standard setup for smaller trailers, utility trailers, and light-duty towing, giving you exactly what you need to tow safely.
No factory tow package? No problem. This harness works without a converter, making it an easy add-on for vehicles that didn’t come pre-wired for towing. It’s built to supply the right signals straight from your existing wiring.
