2 Pack 40/30 AMP 12V DC Waterproof 5-Pin SPDT Automotive Relay Kit with Heavy-Duty Tinned Copper Pigtail Harness, for Car Truck Motorcycle Boat Headlight Fog Light Fan

["【Premium Heavy-Duty Wiring】Primary leads use 14 AWG tinned copper wire and coil leads use 18 AWG tinned copper wire, ensuring low resistance, excellent conductivity, and resistance to heat, corrosion, and vibration. Perfect for high-load 12V DC applications such as headlights, fog lights, fans, pumps, and horns.","【Reliable Electrical Specifications】Nominal Coil Voltage: 12 V DC; Coil Power: 1.8 W; Coil Resistance: 80 Ω; Must Operate Voltage: 6~8 V DC; Must Release Voltage: 0.6~3.6 V DC; Maximum Applied Voltage: 15.6 V DC. Always stay 10 to 15% below the rated current to extend the relay’s lifespan.","【Waterproof & Dustproof Design】The fully sealed housing offers excellent water-repellent and dustproof performance, suitable for harsh environments like engine bays and off-road vehicles. Please note: it is water-resistant but NOT waterproof for submersion; do not use it underwater.","【Safe & Easy Installation】Comes with a pre-wired heavy-duty pigtail harness for plug-and-play installation. Be careful when inserting the relay into the socket to avoid forcing it, as this may bend the female connectors and cause poor contact. The included mounting bracket allows for secure placement in tight spaces.","【Versatile 5-Pin SPDT Functionality】Single Pole Double Throw (SPDT) design supports both normally open (NO) and normally closed (NC) circuits, offering flexible wiring configurations. Widely compatible with cars, trucks, motorcycles, ATVs, boats, RVs, and other 12V DC electrical systems."]
