JD1912 Automotive Relay Harness, 40A 12V SPST with Color-Labeled Wires, Heavy Duty Car Relay for Truck Van Motorcycle Boat (Metal 5pin 12V)

This JD1912 automotive relay harness is an essential component for controlling high-current electrical circuits in your vehicle. Designed as a heavy-duty SPST (Single Pole Single Throw) relay, it handles loads up to 40A at 12V DC, making it ideal for automotive, truck, van, motorcycle, and boat applications. The relay features color-labeled wires that simplify installation and prevent wiring errors, ensuring a reliable connection every time. With a compact design and low power consumption of just 1.8W, this relay operates efficiently with a minimum voltage of 8V and standard operating voltage of 12V. The silver alloy contacts provide excellent conductivity with contact resistance of 100 milliohms or less, while delivering an impressive electrical life expectancy of 100,000 operations and mechanical life of 10,000,000 operations. Fast response times of 15ms operate and 10ms release ensure quick switching performance. Built to withstand demanding conditions, this relay operates reliably in temperatures ranging from -67°F to 158°F and maintains high insulation resistance. Whether you're installing auxiliary lighting, cooling fans, or other high-draw accessories, this relay harness provides the durability and performance you need for your electrical system upgrades.
