Decoding Your 1991 Toyota Pickup Tail Light Wiring Diagram
The 1991 Toyota Pickup Tail Light Wiring Diagram is a visual representation of how the electrical current flows from your truck's battery to the tail light assemblies. It illustrates the connections between various components, including the light bulbs themselves, the sockets they fit into, the wiring harness that carries the power, and the switches and relays that control their operation. Understanding this diagram is essential for a few key reasons:- It helps identify the specific wires responsible for each function: tail lights (low intensity running lights), brake lights (high intensity when the pedal is pressed), and turn signals (flashing lights indicating direction).
- It outlines the color-coding of the wires, which is crucial for making correct connections and avoiding short circuits.
- It shows the location and function of fuses and relays, which protect the circuit from electrical surges.
| Function | Typical Wire Color |
|---|---|
| Tail Lights (Running Lights) | Brown |
| Brake Lights | Red |
| Left Turn Signal | Yellow |
| Right Turn Signal | Green |
