The JD1912 Car Relay Harness is a reliable 12V 40A automotive relay designed for high-current switching applications in trucks, vans, motorcycles, and other DC-powered vehicles. Featuring a 4-pin SPST configuration, this relay handles demanding loads such as horns, lights, fans, and other general-purpose automotive accessories with ease. The pre-wired 12AWG harness socket comes with color-labeled wires — yellow, black, red, and white — making identification straightforward and helping reduce wiring errors during installation. The compact relay body measures approximately 0.98 x 1.06 x 1.10 inches, while the harness socket measures 1.10 inches wide with a total wire length of 4.92 inches. A metal mounting bracket (0.59 x 1.57 inches) is included for secure, fixed installation. Rated for low-voltage DC systems below 75Vdc, this relay delivers consistent and dependable switching performance. The 4-pack set ensures you have spares on hand for multiple projects or replacements, making it a practical choice for any automotive wiring setup.
