India’s EV Shift Creates Growth for Wiring and ECU Makers
Indian two-wheelers are using more electronics and electric parts.
This means they need more wires, sensors, controllers, and other components.
Electric scooters can require several times more wiring value than petrol scooters.
Dhoot Transmission makes wiring harnesses and has a large share of this market.
SEDEMAC makes electronic control units that help vehicles operate.
Both companies are growing as manufacturers add more technology to their vehicles.
They are also building new factories and increasing production capacity.
However, investors are paying high prices for their shares, so weak execution could be risky.
India’s domestic two-wheeler wiring-harness market is projected to grow at a 14% CAGR from FY26 to FY31.
Electric two-wheeler wiring-harness demand is expected to expand 38–41% annually, compared with 8–10% for ICE vehicles.
Dhoot Transmission holds a 38% share of India’s two-wheeler wiring-harness market and reported ₹1,446.4 crore revenue in Q1FY27.
SEDEMAC accounted for 80% of India’s two- and three-wheeler ISG market-volume growth in FY26.
Both companies are expanding capacity, but their premium valuations leave limited room for execution errors.

Growth case
Valuation and execution risks
Electric-vehicle expansion
Growth case
Rising EV adoption should increase demand for wiring harnesses, battery assemblies, controllers, sensors, and other higher-value components.
Valuation and execution risks
The companies’ premium valuations leave limited room for slower EV adoption, weaker volumes, or execution mistakes.
Business positioning
Growth case
Dhoot has wiring-harness leadership, while SEDEMAC supplies products across both internal-combustion and electric platforms.
Valuation and execution risks
Future returns depend on successfully ramping new models, facilities, and EV products while managing supply-chain and raw-material pressures.
Financial performance
Growth case
Both companies reported strong Q1FY27 growth, with SEDEMAC’s net profit rising 95% and Dhoot’s rising 37.8%.
Valuation and execution risks
SEDEMAC’s Q1FY27 EBITDA margin was slightly compressed by semiconductor supply tightening and higher raw-material costs.
