Features to Know About

Straightforward Installation, But Plan for Access

The vehicle's wiring harness is often behind a trim panel or under the cargo floor. Some vehicles may require removing interior panels or lifting carpeted sections to reach it, but once accessed, the harness installs easily with quick-splice connectors.

No Cutting or Splicing Needed: Custom-Fit T-Connector

Plugging in a trailer shouldn't mean tearing into your vehicle's wiring. This custom-fit T-connector snaps directly into your factory wiring harness, so you can get your trailer lights up and running without any cutting or splicing. Just plug it in, and you're ready to tow.

Reliable Trailer Lighting for Every Trip: Powers Brake, Turn, and Running Lights

A well-lit trailer is a safe trailer. This 4-way wiring harness keeps your trailer's brake lights, turn signals, and running lights powered and in sync with your vehicle. Whether you're hauling a boat to the lake or a camper to the mountains, your lights stay bright and visible.

Prevents Overloaded Circuits: Powered Converter for Safe Towing

Some vehicles can't handle the extra electrical load of trailer lights. The built-in powered converter draws power directly from your battery, ensuring a steady, protected current to your trailer while keeping your vehicle's circuits from overloading.

Keep Wires in Check: Fully Insulated and Weather-Resistant

Towing means exposing your wiring to dirt, rain, and road grime. This harness features fully insulated wires and a sealed converter, helping to prevent shorts and corrosion. It's built to withstand the elements so you can tow with confidence in any weather.

Everything You Need for a Clean Install: Complete Kit Included

No extra trips to the hardware store - this kit comes with everything you need. With fuses, zip ties, and connectors included, you can complete the installation without hunting down extra parts.

The harness for my 2026 Kia Sorento EX hybrid fit perfectly. Be forewarned to be sure you get the right harness, sometimes the product descriptions can be a little misleading. Personally I don’t think they do a very good job describing which vehicles they fit.

  • Parts Needed to Add 7-Way to 2025 Kia Sorento
    Hey Cynthia! We don't have a European 13-pole but we do have what you need to add a 7-way and 4-way to your 2025 Sorento. If you do not have LED tail lights you need the Curt # C63RV. If you have the SX with LED lights then you need # C34FR73HY instead. Since a plug and play 7-way is not available, you can upgrade the Curt 4-way to a 7-way using the Universal Installation Kit # ETBC7. This comes with the adapter, wiring, breakers, and everything else required to convert your 4-way to...

  • Trailer Hitch & Plug And Play Wiring For A 2026 Kia Sorrento Hybrid
    Hi Jim, congrats on the new ride! ^___^ We have just what you are looking for! To start, I recommend the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C37RV. This has a 2" receiver, so you have a ton of options for accessories (bike racks, cargo carriers, etc), and with the 4,000 pounds of towing capacity and 600 pounds of tongue weight capacity, it will carry and pull whatever you need it to. However, this is going to be rated higher than your vehicle, so I encourage you...
