Dual-Relay Versatility, Wide Application Range: Adopting a professional-grade SPDT (Single Pole Double Throw) design, it features dual-relay versatility and can be used as a fuel pump relay, cooling fan relay or LED flasher relay. Compatible with 12V 4-pin automotive relay systems, it works with car lights, horns, starters, wipers, traction control systems and more. Its application covers sedans, trucks, marine vessels, off-road vehicles and household circuits, meeting various electrical needs
IP65 Waterproof and Dustproof: The kit's shell is made of durable insulating material, and the terminals is sealed with sturdy caps and rubber rings for tight connection. It works stably in scenarios like humid conditions, muddy roads or dusty areas, and is suitable for harsh environments such as cars, trucks, marine vessels and off-road vehicles, ensuring reliable operation of equipment like fuel pumps and cooling fans.​
Built-in Diode, Reliable Conductivity and Durability: It comes with color-coded wire harnesses – Pin 87 (blue), Pin 30 (red) are 12AWG, while Pin 85 (black) and Pin 86 (white) are 16AWG. All wires are made of tinned copper, offering excellent conductivity and durability. They can handle high current loads of 40A NO / 30A NC at 14VDC, and an integrated flyback diode protects the circuit from damage, enhancing safety and stability in use.​
Plug-and-Play Design, 5-Minute Quick Installation: The wire harness uses color coding (Red = Pin 30 Battery +, Blue = Pin 87 Load, Black = Pin 85 Ground, White = Pin 86 Switch) and is equipped with a standardized 12V fuse holder. The clear and intuitive wiring allows for 5-minute quick installation without complex operations, greatly reducing installation difficulty and saving time and labor costs, even for beginners.​
High-Performance Upgrade, Complete Kit Accessories: As a direct replacement for 12V relay systems, it outperforms OEM specifications, operating temperature range of -40°C to +125°C, suitable for electric fans, radiator controls and high-current devices. The kit includes 1 waterproof SPDT 4-pin relay (with 130mm pre-wired harness), 1 set of heat-shrinkable wire connectors and 1 set of mounting screws, providing all necessary accessories for one-stop installation and use.
