Many MG and Citroen vehicles sold in India come with a single horn configuration from factory. While functionally adequate, owners often prefer upgrading to a dual horn setup for better tone balance and improved road presence. The issue is not the horn itself — it is the wiring.
Most dual horn upgrades in the market involve cutting factory wires, adding tap connectors, or manually splicing additional leads. These practices compromise insulation integrity, create potential voltage drop, and introduce long-term reliability risks. For vehicles still under warranty, cut wiring can also become a concern.
The TecUpdater MG & Citroen dual horn splitter is engineered to solve this correctly.
It connects directly to the vehicle’s original horn coupler and splits the output into two properly terminated horn connectors. The harness uses 1.5 sqmm automotive-grade copper wiring — suitable for handling standard dual horn electrical loads — and is insulated for Indian climate conditions.
No cutting.
No splicing.
No exposed joints.
It preserves factory wiring while enabling a clean dual horn installation.
Dual Horn Splitter Harness For MG & Citroen — Overview

What It Is
A plug-and-play dual horn splitter harness designed for MG and Citroen vehicles using the standard factory horn connector.
One end connects to the original horn socket in the car.
The other end provides two horn output connectors wired in parallel to operate two horns simultaneously.
Brand: TecUpdater.
What Problem It Solves
Factory single-horn setups create three common issues:
- Limited acoustic presence.
- Owners resorting to unsafe wiring modifications during upgrades.
- Voltage drop caused by thin extension wires or improper splicing.
This harness addresses those issues by:
- Preserving OEM wiring integrity
- Providing correct wire gauge for standard dual horns
- Eliminating the need for cutting factory insulation
- Maintaining clean electrical distribution
It allows installers and vehicle owners to upgrade responsibly without compromising factory architecture.
Installation Logic
Installation is straightforward:
- Locate the factory horn connector.
- Disconnect it from the original horn.
- Connect the vehicle’s factory socket into the input side of this splitter.
- Connect the two output connectors to the two horns.
- Secure both horns and route wiring safely.
No wire cutting required.
No relay required for standard OEM-type dual horns.
No coding required.
No modification to BCM or fuse box required.
If installing high-draw aftermarket trumpet horns or air compressor-based systems, a dedicated relay harness is recommended instead of a direct splitter.
Behaviour Explanation
This harness distributes the existing horn signal to two horns in parallel.
It does not amplify voltage.
It does not increase current supply beyond factory limits.
The 1.5 sqmm copper wiring ensures proper current handling for standard dual horn configurations typically used in passenger vehicles.
The factory fuse rating remains unchanged. Total horn load must remain within safe operating limits.

No wire cutting is needed. You locate the factory horn connector, disconnect it from the original horn, plug the vehicle’s factory socket into the input side of this splitter, then connect the two output connectors to your two horns and secure them in place.
It uses a factory-match MG and Citroen horn coupler on the input side and 1.5 sqmm automotive-grade copper wiring for the dual horn outputs, insulated for Indian climate conditions.
No. This splitter is meant for vehicles with the standard single-horn coupler. It is not intended for cars already equipped with a factory dual horn harness or with previously modified horn wiring.
No. This splitter is built for standard OEM-type dual horn loads. High-power air horn or compressor systems need a dedicated relay-based circuit rather than a direct splitter.
