Technical Details and Compatibility

The EFL-4 relay from Standard Ignition features a male connector and five male blade terminals, designed to integrate seamlessly with your vehicle's existing wiring harness. Its flasher function supports the engine water pump's electrical demands, helping maintain optimal engine temperature. This relay is compatible with numerous vehicles such as the Ford Explorer Sport Trac, Dodge Ram 1500, and Mazda B2300, making it a versatile replacement part for engine cooling systems.

Installation Notes and Tips

Installation of the Standard Ignition EFL-4 relay requires basic electrical knowledge. Ensure the vehicle's battery is disconnected before replacing the relay. The male blade terminals should be connected firmly to the corresponding female terminals in the wiring harness. Since mounting brackets are not included, secure the relay in a location that prevents vibration and exposure to moisture. Verify compatibility with your specific vehicle model before installation.
