2. Identify the wires that connect to the low beam headlights and splice into these wires using wire connectors.
3. Route the fog light wiring harness through the engine compartment and connect it to the spliced wires.
4. Connect the other end of the fog light wiring harness to the fog lights using wire connectors.
5. Connect the fog light switch to the wiring harness using wire connectors.
6. Install the fuse tap into the fuse box and connect the fuse wire to the positive terminal of the battery.

FAQs
1. Do I need to install a relay for the fog lights?
Yes, it’s recommended to install a relay for the fog lights. A relay is a device that allows a small current to control a larger current, which is required to power the fog lights. Without a relay, the wiring and switch may become hot or overloaded, which can pose a safety hazard.
2. How do I test the fog lights after installation?
You can test the fog lights by turning on your vehicle’s low beam headlights and activating the fog light switch. The fog lights should turn on and provide additional illumination. If the fog lights don’t turn on, check the wiring connections and the fuse.
3. Can I install aftermarket fog lights on my 2004 Silverado?
Yes, you can install aftermarket fog lights on your 2004 Silverado. However, make sure to choose fog lights that are compatible with your vehicle’s electrical system and mounting location. Also, follow the manufacturer’s instructions carefully and use high-quality equipment for the best results.
4. How do I adjust the fog lights after installation?
You can adjust the fog lights by using the adjustment screws located on the back of the fog lights. Park your vehicle on a level surface and turn on the low beam headlights. Use a wall or a solid object as a reference point and adjust the fog lights until the beam pattern is level and in the desired direction.
5. Are fog lights legal to use on public roads?
Yes, fog lights are legal to use on public roads, but they should only be used when visibility is significantly reduced due to weather conditions such as fog, rain, or snow. Using fog lights in clear weather conditions can be dangerous and may blind other drivers on the road.
In conclusion, installing fog lights on your 2004 Silverado can improve your visibility and safety on the road. By following the steps and tips provided in this article, you can wire your fog lights properly and enjoy the benefits of enhanced illumination during bad weather conditions.
