Product Description
Customized 40A 12V Waterproof Relay Plug Harness for Automotive & New Energy Vehicle Wiring (SW-W-10)
40A Waterproof Relay Plug Harness — One Sealed Unit, No Loose Wiring
Relays live in the worst corners of a vehicle — engine bays, chassis wells and battery compartments, where moisture, dust and vibration slowly corrode ordinary plug connections until the circuit drops out. The Snowwolf SW-W-10 answers with an integrated design: a 40A relay and its socket pre-built into one sealed, plug-ready harness, so the switching function arrives assembled, waterproofed and ready to connect.
Each unit combines the relay, socket and pre-arranged wiring in a single assembly. Conductors are laid out professionally and wrapped in durable insulating material, keeping the loom tidy, protected and easy to route through tight panels. The sealed plug construction maintains stable performance in wet and harsh conditions, while the integrated layout shortens installation time on the assembly line and in the service bay. Wiring colors, lengths and gauge can be customized to your vehicle platform.
The SW-W-10 is manufactured in our ISO/TS 16949-certified factory in Dongguan with ROHS & YACE-003 compliance, 100% inspection before packing and a 1-year warranty. Orders start at 100 pieces with 15–25 day delivery and 50,000-piece monthly capacity. For custom relay specs, wire harness layouts or private labeling, send your inquiry — our engineers reply with a proposal within 24 hours.
