Wiring Diagram For A Relay Fog Lights

Wiring diagrams can be a daunting task for many people. But, if you understand the fundamentals of a wiring diagram, then connecting the fog lights to a relay can be a simple job. Knowing how to properly wire a relay for fog lights can go a long way in protecting your vehicle and providing visibility in low light conditions.

A relay is an electrical switch that allows a low-power current to control a higher-power current. When it comes to wiring fog lights to a relay, you need to know both the control circuit and the load circuit. The control circuit is the one that will provide the power from the switch. The load circuit is the one that will send the power to the fog lights.

The first step to wire a relay for fog lights is to connect the positive wire from the switch to the 86 terminal on the relay. Then, take the negative wire from the switch and connect it to the 85 terminal on the relay. Next, connect the positive wire from the battery to the 30 terminal on the relay. This will provide power to the relay. Finally, connect the positive wire to the fog lights to the 87a terminal on the relay. If the fog lights have a ground wire, connect it to the chassis of the vehicle.

These steps should get your fog lights wired to the relay, but it’s important to double-check your connections before powering up the system. By following these instructions, you can ensure that your fog lights will be connected safely and properly. After you’ve wired the fog lights to the relay, you should be able to enjoy improved visibility and a safer driving experience.
