This 4-pack 12V automotive relay kit is built to handle the demanding electrical needs of cars, trucks, motorcycles, boats, and vans. Each relay features a 4-pin SPST configuration rated at a robust 40 amps, making it well-suited for controlling high-current circuits with confidence. The durable copper contacts ensure reliable switching performance, while the compact 1.8-watt coil operates efficiently at 12 volts without placing unnecessary strain on your vehicle's electrical system. Installation is straightforward thanks to the pre-installed, color-coded wiring harness — featuring heavy-duty 12 AWG and 16 AWG wires — that plugs directly into the included harness sockets for a quick and secure connection. A screw mount design keeps each relay firmly in place once installed, and the automatic operation mode means no manual intervention is needed during use. The clearly labeled pin diagram (85, 86, 30, 87) printed on each relay body makes wiring simple even for first-time installers. Whether you're upgrading your vehicle's lighting, horn, fan, or other accessories, this relay kit delivers dependable performance in a convenient multi-pack.
