5Pcs Waterproof Automotive Relay 12V 5Pin 40A Car Relay with Black Red Copper Terminal Auto Relay Socket SPDT Harness Cable (12V)

Keep your vehicle's electrical systems running smoothly with this set of 5 waterproof automotive relays. Each JD1914 relay is rated at 12V and 40A, making them well-suited for controlling radiator fans, headlights, horns, and other high-current automotive circuits. The SPDT 5-pin design provides versatile switching capability, supporting both normally open and normally closed configurations to fit a wide range of applications. High-conductivity copper terminals help minimize heat buildup and power loss, ensuring reliable performance over time. The waterproof construction shields each relay against moisture, dust, and vibration — common challenges in automotive environments. Each unit measures approximately 20mm x 30mm with an 180mm harness cable, and comes complete with a relay socket and pre-wired harness for a quick, plug-and-play installation. Compatible with 12V and 24V systems, these relays are a practical choice for cars, trucks, and boats alike. The mounting bracket on each relay allows for secure, fixed installation wherever needed. A must-have addition to any automotive electrical toolkit.
