Decoding Your 73 87 Chevy Truck Tail Light Wiring Diagram
The 73 87 Chevy Truck Tail Light Wiring Diagram is essentially a roadmap for how electricity flows to your truck's rear lighting system. It illustrates the connections between the tail light bulbs, brake light bulbs, turn signal bulbs, and the various switches and relays within your truck. This diagram is an indispensable tool for anyone looking to diagnose lighting issues, perform repairs, or even upgrade their tail lights. Whether you're dealing with a burnt-out bulb, a flickering turn signal, or a complete system failure, the wiring diagram provides the foundational understanding needed to pinpoint the problem and implement a solution. Having a clear understanding of this diagram is of utmost importance for ensuring your vehicle is safe to operate and complies with all traffic regulations.
Understanding the diagram involves familiarizing yourself with its components and symbols. You'll typically find representations for:
- Tail lights (running lights)
- Brake lights
- Turn signals (left and right)
- Reverse lights (on some models)
- Ground connections
- Fuses and relays
The diagram will show the specific wire colors used for each function, as well as the pathways they take from the power source, through the switches, and finally to the bulbs. For example, a typical setup might involve:
- The main power source (battery)
- The headlight switch, which controls the tail lights when the headlights are on
- The brake light switch, activated by pressing the brake pedal
- The turn signal switch (flasher unit), which activates the left or right turn signals
- The bulbs themselves, housed within the tail light assemblies
Here's a simplified look at common wire functions:
| Wire Color (Typical) | Function |
|---|---|
| Brown | Tail Lights / Running Lights |
| Red | Brake Lights |
| Yellow/Orange | Left Turn Signal |
| Green/Blue | Right Turn Signal |
| Black | Ground |
It's important to remember that wire colors can vary slightly between model years and specific trim levels, so always cross-reference with your truck's specific documentation if possible. However, the fundamental principles of electrical flow remain consistent across the 73-87 generation.
Having the correct 73 87 Chevy Truck Tail Light Wiring Diagram readily available is your key to successful troubleshooting and maintenance.
