MG entered the Indian market relatively recently, and the aftermarket parts ecosystem for models like the Hector is still catching up compared to older, higher-volume brands. One area where this shows up is horn upgrades — owners wanting a deeper or louder tone often find that horn kits sold for Hyundai, Kia, or VW don’t have a connector that matches the MG’s factory plug.
What This Harness Does
The adapter below takes the factory single-horn connector on your MG Hector (or similar MG model) and gives you a standard 2-pin output — the same terminal style used by widely available aftermarket horns, including the Hella Chrome Trumpet set. In effect, it removes the connector mismatch as the blocker.
Quick Answers
- Cutting required? No — it’s a plug-in connector swap, factory wiring stays untouched.
- Relay changes? Not needed for a standard horn upgrade. The existing relay and fuse continue to run the circuit.
- Reversible? Yes — refit the original horn and connector and the car is back to stock.
- Electrical load concern? No. A horn upgrade like this draws current only momentarily, when pressed, well within what the factory circuit is built for.
- Horn brands it works with? Any horn with a standard 2-pin terminal, including Hella Chrome Trumpet sets.

Converts the MG factory horn connector to a standard 2-pin terminal, opening up the wider range of aftermarket horns built for that format.
Bottom Line
For MG owners, this adapter is less about adding a second horn and more about being able to use the same popular aftermarket horns that already work on other brands — without an electrician rewiring the connector by hand.
