Specifications & Compatibility

The TecUpdater Single to Dual Horn Splitter Harness (Hyundai/Kia INFAC Type) is designed for vehicle owners and installers who want a clean, professional horn upgrade without touching or altering factory wiring. Many users search for solutions like a plug and play horn adaptor, single to dual horn converter, or automotive horn connector when upgrading their horn system. This harness replaces all those temporary methods with a proper OEM-standard setup.

It enables the use of dual INFAC-type trumpet horns found in popular Hyundai and Kia models such as Creta, Seltos, Venue, Sonet, Carens, Verna, Alcazar, and more. Whether you are performing a Hyundai Dual Horn Installation, a KIA Dual Horn Installation, or completing a Kia Seltos horn upgrade, this harness allows the same dual high–low configuration to be used in any vehicle that originally came with a single horn.

This plug-and-play harness converts the existing horn socket into two OE-spec INFAC connectors, making the installation of dual horns safe and neat. For customers searching terms like HYUNDAI horn coupler cable, Hyundai horn socket, INFAC horn connector, INFAC horn splitter, or Kia horn wiring harness, this harness matches exactly those specifications.

Dual Horn Installation Process

1. Remove Existing Horn
   Locate and remove the stock horn along with its single wiring connector.
   This process is identical to what is done during Hyundai Creta horn wiring or dual trumpet horn wiring upgrades.

2. Prepare the Dual Horn Harness
   Identify the input side (single connector) and output side (dual INFAC connectors).

3. Connect to Car Horn Cable
   Plug the input connector into the vehicle’s factory horn cable. No splicing or wire cutting is needed, unlike a universal horn harness or local horn splitter wire.

4. Mount the Horns
   Install both horns at suitable mounting points, ensuring downward-facing orientation to avoid water accumulation.

5. Check & Test
   Ensure all terminals are secure and test both horns together.

OEM-Grade Fit & Finish

Built to match Hyundai and Kia factory standards, this harness uses precision-molded INFAC connectors with corrosion-resistant, vibration-proof metal terminals. It is engineered for those who prefer an OEM horn wiring approach instead of aftermarket cutting or rewiring.

Fitment is tight, secure, and designed to withstand moisture, dust, heat, and engine bay vibrations. This layout is especially helpful in vehicles where horns sit behind the bumper or radiator shroud.

Premium Construction Quality

Each TecUpdater harness is built to professional-grade standards:

• High-conductivity copper wiring for minimal voltage loss

• OE-grade insulation with heat-resistant outer wrapping

• Strain-relief design to prevent connector fatigue

• Precision crimped terminals (not soldered)

• Fully tested for continuity and polarity

These qualities make it a superior choice over a typical car horn extension cable, car horn upgrade kit, or universal horn harness commonly used in workshops.

Effortless Plug-and-Play Installation

No cutting, no splicing, and no relay required (unless upgrading to high-power setups). The design supports all INFAC-style Hyundai and Kia dual trumpet horns. Whether you need compatibility for Hyundai/Kia horn harness, Hyundai universal horn harness, or TecUpdater INFAC harness standards, this unit supports them all.

Most installations take less than five minutes using standard tools.

Long-Term Reliability

This harness is engineered to withstand:

• Engine bay temperatures

• Water splash and dust exposure

• Voltage variation in 12V automotive systems

• Daily use in city and highway conditions

It is ideal for professional installers, automobile enthusiasts, and vehicle owners looking for an OEM-grade horn upgrade solution.
