Specifications & Compatibility

The TecUpdater Single to Dual Horn Splitter Harness (Hyundai/Kia INFAC Type) is designed for enthusiasts who want to upgrade their horn system professionally — without tampering with the factory wiring.
It enables the use of dual INFAC-style horns found in popular Hyundai and Kia models like Creta, Seltos, Venue, Sonet, Carens, Verna, and more — in any vehicle that originally came with a single horn setup.

This plug-and-play harness converts your existing horn socket into two dedicated INFAC-type connectors, allowing installation of both high-tone and low-tone horns safely, neatly, and reliably.

OEM-Grade Fit & Finish

Built to match Hyundai/Kia factory specifications, this harness uses precision-molded INFAC connectors with secure locking tabs and corrosion-resistant terminals.
The fit is snug and clean, ensuring consistent electrical contact and long-term reliability even under heat, moisture, and vibration.

The harness layout is compact and flexible — ideal for routing around the front bumper or radiator area where horns are typically mounted.

Premium Construction Quality

Each TecUpdater harness is engineered to professional standards:

• High-conductivity copper wiring for minimal voltage drop.

• OE-grade insulation using heat-resistant PVC and protective tape wrapping.

• Factory-style sealing and strain relief to prevent water ingress.

• Crimped terminals (not soldered) for vibration-proof, consistent contact.

Every piece undergoes manual testing for polarity and continuity before packaging, ensuring 100% readiness for installation.

Effortless Plug-and-Play Installation

No wire splicing, no cutting, no relay needed (though compatible if used).
One end of the harness connects to your vehicle’s existing horn plug, and the other two connect directly to the INFAC-type dual horns. The horns then operate as a synchronized high-low pair, producing a richer, more authoritative tone.

Installation typically takes under 5 minutes using standard tools.

Reliable, Long-Lasting Design

This harness is engineered to withstand:

• Engine bay heat and vibration

• Moisture and dust ingress

• Voltage fluctuations in 12V and 24V setups

It’s an ideal choice for daily-use vehicles, enthusiasts, and professional installers seeking OEM-grade wiring upgrades.
