The General Engine Main Harness from Danyang Winpower is a high-performance wiring solution engineered to supply stable, efficient, and reliable electrical power to every essential component within an engine system. Designed for automotive, industrial, marine, agricultural, and generator engines, our harness ensures seamless communication between sensors, actuators, ignition systems, fuel injectors, ECU modules, alternators, starters, and critical electrical subsystems.

Manufactured using high-strand copper conductors and automotive-grade, heat-resistant insulation, the harness is built to handle extreme temperature fluctuations, vibration, oil exposure, and mechanical stress commonly found in under-hood environments. Each wiring bundle is routed, grouped, and protected with premium materials such as PVC tubing, corrugated loom, braided sleeving, or fabric tape to provide long-term abrasion resistance and improved installation convenience.

As a professional custom wiring harness manufacturer, Danyang Winpower offers complete OEM/ODM services, including:

• Custom wire gauges (0.5mm²–35mm² / AWG equivalent)

• Dedicated connector brands (AMP/Tyco, Sumitomo, Yazaki, Molex, Deutsch, TE, etc.)

• Waterproof protection (IP67/IP68 sealing options)

• High-temperature materials (XLPE, PVC, TPE, silicone)

• Custom terminal crimping, pin layouts, and locking systems

• 2D/3D harness design and sample prototyping

• Multi-harness integration for complete engine systems

Every General Engine Main Harness is subjected to strict quality control—continuity testing, resistance testing, tensile pull force checks, dielectric strength testing, and environmental simulations—to ensure dependable performance and extended service life in demanding applications.

With advanced manufacturing capabilities and stable supply chain management, Danyang Winpower supports global OEMs, vehicle manufacturers, equipment producers, and aftermarket suppliers seeking high-quality, customizable engine wiring solutions.
