2020 Chevy Silverado Aux Switches: A Comprehensive Guide (Part Number 84688686)
The 2020 Chevy Silverado offers a range of customization options, and adding auxiliary switches is a popular upgrade for serious off-roaders, truck enthusiasts, and anyone wanting to expand their vehicle's functionality. This guide focuses on the common auxiliary switch setup, often associated with part number 84688686, and will answer many frequently asked questions surrounding its installation and use.
What are Auxiliary Switches and Why Would I Need Them?
Auxiliary switches provide additional circuits in your vehicle, allowing you to easily control aftermarket accessories such as:
- Off-road lighting: Work lights, light bars, fog lights.
- Winches: Quickly engage and disengage your winch.
- Compressors: Air suspension or tire inflation systems.
- Heaters: Auxiliary cabin heaters or block heaters.
- Other accessories: Anything requiring an on/off switch and a power source.
Without auxiliary switches, wiring these accessories directly to the battery or other power sources can be complicated, messy, and potentially dangerous. These switches provide a clean, organized, and safe solution. The part number 84688686 typically refers to a factory-style switch bank, but aftermarket options are plentiful.
Where are the Auxiliary Switches Located in a 2020 Chevy Silverado?
The location of your auxiliary switches depends on your trim level and whether you opted for the factory-installed switch bank. Some models incorporate them into the overhead console, while others may require aftermarket installation. If you have the factory-installed switch bank (often associated with the part number 84688686 or similar), it's usually found in the overhead console, providing easy access while driving. If you do not have a factory switch bank, you'll need to choose an installation location and potentially add a switch panel yourself.
How Do I Install Auxiliary Switches in My 2020 Chevy Silverado?
Installing auxiliary switches in your 2020 Silverado can range from simple plug-and-play (if you purchased a factory-compatible kit) to more involved custom installations. If you're using the part number 84688686 or a similar factory kit, the installation should be relatively straightforward, often involving plugging into existing wiring harnesses. However, if you're installing an aftermarket switch bank, you will need to:
- Choose a location: Consider ease of access and visibility.
- Run wiring: This often involves carefully routing wires through the vehicle's firewall and interior.
- Connect to a power source: This typically involves connecting to a fused power source to prevent overload.
- Connect to the accessories: Make sure to follow the wiring diagrams for your specific accessories.
Always consult a professional electrician or follow a detailed installation guide if you're uncomfortable with electrical work. Improper wiring can lead to serious damage or even fire.
What is the Difference Between a Factory Switch Bank and an Aftermarket Option?
The main difference lies in integration. A factory switch bank (like the one potentially associated with 84688686) is designed specifically to fit seamlessly into the vehicle's existing system, often with simple plug-and-play installation. Aftermarket options offer greater flexibility in terms of design, number of switches, and features but may require more extensive installation. They might also lack the seamless integration of a factory-installed system.
Can I Add Auxiliary Switches Myself, or Should I Hire a Professional?
While many individuals can successfully install auxiliary switches themselves, it's crucial to possess a good understanding of automotive electrical systems. If you're not comfortable with wiring and electrical work, it's best to hire a qualified professional. Incorrect wiring can damage your vehicle's electrical system or even create a fire hazard.
This guide offers a general overview. Always consult your owner's manual and the specific instructions for your chosen auxiliary switch kit for detailed information relevant to your 2020 Chevy Silverado. Remember, safety should always be your top priority when working with automotive electrical systems.
