Tata and Mahindra models — Tiago, Tigor, Punch, Nexon, Altroz, Harrier, and Safari, along with several Mahindra models — share a Delphi-type single horn connector at the factory. This connector doesn’t directly match the INFAC plugs used by Hyundai/Kia or the OEM plugs used by VW/Skoda, which is usually the first thing owners discover when they try to fit a dual horn kit bought for a different brand.

Common Questions

Why doesn’t a generic dual horn kit fit straight onto my Nexon or Harrier?
Because the factory plug is Delphi-type, not the INFAC or universal-pin format most generic kits assume. A conversion harness is the part that bridges this gap — it takes the Delphi plug on one end and gives you either an INFAC connector or universal pigtails on the other.

What if I want to use INFAC-type horns from a Creta or Seltos on my Tata?
That’s exactly what the INFAC variant of the harness below is for — it lets you run those horns on the Delphi-equipped Tata/Mahindra platform.

What if I’m using Hella, Minda, or Bosch horns instead?
Use the universal pigtail variant. It gives you generic terminal ends that connect to most aftermarket dual horn sets without needing an INFAC-specific horn.

Does fitting this harness require cutting into the Tiago’s or Punch’s wiring loom?
No. It’s a connector-to-connector swap — unplug the factory horn, plug in the harness, plug your horns into the other end.

Will this trip a fuse or strain the alternator on my Altroz or Safari?
No. The harness wiring matches the factory gauge, and the existing horn relay and fuse continue to handle the circuit exactly as before — you’re changing the connector, not the electrical load characteristics of the circuit itself.

The Harness You Need

Delphi to Horn Harness for Tata and Mahindra – INFAC Dual Horn and Universal Thimble Options

One harness, two variants: pick the INFAC option to run Creta/Seltos-type dual horns, or the universal pigtail option to wire in Hella, Minda, Bosch, or other generic dual horns on your Tata or Mahindra.

Bottom Line

If you’ve already bought a dual horn set that doesn’t plug into your Tata or Mahindra, this harness is almost certainly the missing piece — it’s the adapter between the Delphi connector your car was built with and whatever horn standard you’re trying to use.
