Description

  • Dual-Circuit Reliability (2 Pack): Double the protection for your high-power upgrades. This 2 Pack 40A 12V Starter Relay Switch is specifically bundled for dual-load applications like twin cooling fans, dual horns, or off-road light bar arrays. Having a spare Auto Relay on hand also ensures you’re never stranded by a single component failure during long hauls.
  • Authentic JD2912-1H Standard: Stop struggling with poorly-sized pins. Our JD2912-1H-12VDC relays are engineered to the exact ISO footprint, ensuring a perfect "click-in" fit for all standard 4-pin sockets. The rugged SPST Design (Single Pole Single Throw) provides a clear, reliable path for high-current switching in any Automotive Application.
  • Heavy-Duty Copper Wiring: Engineered for zero-compromise power delivery. Each kit features a Wire Harness with 100% Heavy-duty Copper pigtails. We use 12AWG leads for the primary load to handle the 40A capacity safely, minimizing voltage drop and preventing the dangerous heat buildup common in low-grade copper-clad aluminum (CCA) alternatives.
  • Robust Weather-Resistant Construction: Built to survive the engine bay environment. The relay housing is made from premium flame-retardant materials that resist warping under high temperatures. Combined with the Harness Wires, this setup acts as a Safe and Reliable hub, shielding your electrical connections from dust, vibration, and moisture in Marine or Truck environments.
  • Simplified DIY Installation: Get your project moving faster. Our Relay Switch set features a color-coded Wire Harness for intuitive wiring: Blue (30) to Battery, Red (87) to Load, Black (85) to Ground, and White (86) to Switch. This "plug-and-play" logic reduces installation errors and ensures a professional, factory-clean look under your hood.
