How to Install Fog Lights: The Step-By-Step Guide

How to Install Fog Lights: The Step-By-Step Guide

Get to the battery and disconnect the negative terminal.

Lay the wiring in the layout you want while avoiding any areas that can get in the way.

Under the steering wheel, you will find the interior panels. Handle these parts with care and remove the fuse access panel by hand. Another panel that is below the steering column should be unbolted.

Now you can choose the location for the switch. It should be a location that is easily accessible.

Go to the ground and look for other ground wires. You would find a bolt going through metal. You need to remove this bolt and slide the ground connector and retighten the bolt.


Find an empty fuse of 12V by using the voltmeter when the engine is on. Find the fuse and connect the positive connector. This will turn the fog lights on and off when the engine is on and off.

Now going further on how to wire fog lights, take the wiring through the firewall, you can use a coat hanger if the firewall seems stiff enough.

Here you connect the on/off switch wiring to the engine bay wiring. Any excess wiring should be bundled and put in the interior panels so it doesn’t come in the way.

Now you need to make the connection to the location of the fog lights or where you would install the fog lights. You may find an open space behind the headlights, and you may also need to remove the fender to access it from the other side.

When the piece is removed, you will access the space when the fog lights can be equipped. Use a plastic trim removal tool to take off the plastic cover if it doesn’t come off manually. Just connect the wiring connections on each side and you are done.

Make sure you connect the positive lead to the positive battery terminal and connect the fog lights to the wiring.

Before bolting these lights, you can run a test to check if everything works fine. Reconnect the negative battery terminal that you disconnected before starting the process. You will know if the fog lights are working while performing the test. Later, you can bolt everything and arrange it neatly.

Whether you are replacing the fog lights or installing them in a vehicle that never had fog lights, always install them on the lower half of your front end. These lights should exist below the headlights, or measuredly, 10 to 24 inches above the ground. Remember that fog usually starts about 2 feet off the ground, it would be better if you install fog lights below that level.
