Wsays 4-Way Flat Trailer Wiring Harness Review: Easy Install for Hyundai, Kia, and More

Towing can be a huge convenience, but ensuring your trailer's lights work correctly is paramount for safety and legality. The Wsays 4-Way Flat Trailer Wiring Harness offers a seemingly simple solution for connecting your trailer lights to compatible vehicles. This review dives deep into its features, benefits, and drawbacks to help you decide if it's the right choice for your towing needs. Specifically designed for select Hyundai and Kia models, including the Santa Fe, Veracruz, Sedona, and Sorento (check compatibility list below), this harness promises a plug-and-play installation, eliminating the need for complex wiring modifications.

Finding the right trailer wiring harness can be a headache. Many aftermarket solutions require splicing wires, a task that can be daunting for some and can potentially void your vehicle's warranty if not done correctly. The Wsays harness aims to bypass these concerns by offering a direct connection to your vehicle's factory tow package, making the installation process significantly easier and safer. This review will assess its ease of installation, build quality, and overall performance to help you make an informed decision.

Key Features

  • • Vehicle-Specific Fit: Designed specifically for Hyundai Santa Fe (2013-2018), Veracruz (2007-2012), Kia Sedona (2015-2021), Sorento (2011-2020), and Sorento (2007-2009) with factory tow package.
  • • 4-Way Flat Connector: Provides standard trailer lighting connections for brake lights, tail lights, and turn signals.
  • • Plug-and-Play Installation: Connects directly to the vehicle's existing tow package wiring, eliminating the need for splicing.
  • • Durable Construction: Built with high-quality materials to withstand harsh weather conditions and road debris.
  • • Protective Cover: Includes a dust cover to protect the 4-way connector when not in use.

Pros

  • • Simplified Installation: The plug-and-play design makes installation incredibly easy, even for those with limited automotive experience. Most users report successful installation in under 30 minutes.
  • • No Wire Splicing Required: Eliminates the risk of damaging your vehicle's wiring system and potentially voiding your warranty, which is a significant advantage over universal wiring kits.
  • • Cost-Effective Solution: At around $34, the Wsays harness offers a budget-friendly way to equip your vehicle for towing, compared to professional installation or more complex wiring solutions.
  • • Vehicle Specific Design: This is great because it bypasses the need for trial and error when trying to hook up a universal kit. This provides peace of mind that your vehicle is properly wired.

Cons

  • • Limited Vehicle Compatibility: Only works with specific Hyundai and Kia models equipped with a factory tow package. Verify compatibility before purchasing.
  • • Durability Concerns: While advertised as durable, some users have reported issues with the connector's longevity, especially in harsh weather conditions. Consider using dielectric grease to protect connections.

Who Should Buy

The Wsays 4-Way Flat Trailer Wiring Harness is ideal for Hyundai and Kia owners who need to tow occasionally and want a hassle-free wiring solution. If you have a compatible vehicle with a factory tow package and are comfortable with basic automotive tasks, this harness can save you time and money compared to professional installation. It's a great choice for those towing small trailers, such as utility trailers, boat trailers, or trailers for recreational vehicles like ATVs or motorcycles.

This harness is not recommended for vehicles without a factory tow package, as it requires the existing wiring for proper connection. It's also not suitable for individuals who need more advanced wiring configurations, such as those required for trailers with electric brakes or auxiliary power. For these more complex towing setups, consider a 7-way connector and professional installation.

If you are unsure if your vehicle has a factory tow package, check your owner's manual or contact your local dealership. Using the wrong wiring harness can damage your vehicle's electrical system, so it's always best to confirm compatibility before purchasing.

Conclusion

The Wsays 4-Way Flat Trailer Wiring Harness provides a convenient and affordable way to connect your trailer lights to compatible Hyundai and Kia vehicles. Its plug-and-play design significantly simplifies the installation process, making it a great option for DIYers. While some users have reported durability concerns, the overall value and ease of use make it a worthwhile investment, especially for occasional towing needs. The ease of installation and vehicle-specific design make this a winner for those seeking a fast and reliable option.

FAQ

Q: Will this fit my [insert vehicle model and year here]?

A: Please check the product description or the Wsays website to ensure your vehicle is listed as compatible. Verify that your vehicle is equipped with a factory tow package before purchasing.

Q: Do I need any special tools to install this?

A: Generally, no. The harness is designed for plug-and-play installation. However, a pair of pliers and dielectric grease can be helpful for securing the connection and protecting against corrosion.

Q: What if my vehicle doesn't have a factory tow package?

A: This harness is not compatible with vehicles that do not have a factory tow package. You will need to explore other wiring solutions that involve splicing into your vehicle's existing wiring. Consider professional installation in this case.

Q: How do I know if I have a factory tow package?

A: Check your vehicle's owner's manual or contact your local dealership. You may also be able to visually inspect your vehicle for a pre-wired connector near the hitch.

Q: Is this harness weatherproof?

A: While the harness is designed to withstand typical weather conditions, it's recommended to use dielectric grease on the connectors to prevent corrosion and ensure a reliable connection. The included dust cover should also be used when the connector is not in use.

The build quality of the Studor 20297 is definitely superior to the generic brands you see at the big box stores. That said, the "Superior Odor Control" is a bit of an exaggeration; it filters about 80% of the scent in my experience. It's a solid product that gets the job done, but at full MSRP, it's a tough pill to swallow for what is essentially a specialized charcoal canister.

Love the RAZARCO brand quality. I’ve tried other Sutherlandia teas before and this one is by far the most potent-feeling. It's a bit of an investment, but if you're serious about herbal support, it's worth it. Plus the packaging is really nice and keeps it fresh.

Used this for a 3-day camping trip in our large tent and it was a lifesaver. It’s way better than sleeping on a thin pad. Just make sure you have a power source for the pump!

Good quality cream but the packaging arrived a bit messy. It works well on the rawhide but the price is a bit steep for the amount you get.
