COMPATIBLE WITH TOYOTA VEHICLES – Fits perfectly on Toyota Corolla (2003-2025), RAV4 (2019-2025 LE/XLE), Tacoma (2016-2024 SR/SR5), Highlander (2020-2025 L/LE), and Yaris Hatchback/Liftback. Ideal for adding a second OEM-style horn to these single-horn models. CONVERT SINGLE HORN TO DUAL – Designed specifically for Toyota vehicles equipped with only one factory horn. This custom splitter harness connects to your original single plug and splits the power to two aftermarket horns (High & Low tone). The perfect solution to fix the weak ""meep-meep"" sound. FOR TOYOTA-SOCKET HORNS ONLY – Designed exclusively for upgrading to ""Lexus-Style"" or ""Premium OEM-Style"" horns that feature the built-in Toyota waterproof socket DOES NOT FIT: Universal aftermarket horns with flat spade terminals unless they have a Toyota adapter. Please check your horn's connector shape before purchasing. FULLY WATERPROOF CONNECTION – Unlike generic spade connectors that leave metal exposed, this harness provides a sealed, watertight connection from end to end. The locking tabs ensure the plugs will never vibrate loose, making it perfect for off-road trucks like the Tacoma or 4Runner. MUST BE GROUNDED TO WORK – Read Before Testing: Many single-pin Toyota-style horns rely on the metal mounting bracket as the negative ground connection. The horn will NOT sound if you simply connect the harness and hold the horn in your air/hand. You must securely bolt the horn to the car's metal chassis to complete the electrical circuit. Please ensure the mounting point is clean and free of rust or heavy paint for a solid ground
