Wiring Color Codes
Before we proceed further, let’s familiarize ourselves with the standard wiring color codes used in the 2000 Chevy Silverado:
| Wire Color | Function |
|---|---|
| Orange | Battery Positive Voltage |
| Pink | Ignition 1 Voltage |
| Yellow | Accessory Voltage |
| Black/White | Ground |
| Black | Ground |
| White | Powertrain Control Module (PCM) |
2. Identifying the Ignition Switch Wires
Now, let’s discuss the different wires connected to the ignition switch and their respective functions:
Wire 1: Orange (Battery Positive Voltage)
The orange wire provides constant battery positive voltage to the ignition switch. This wire is always hot, even when the ignition switch is in the off position. It is typically connected to the fuse box or the battery terminal.
Wire 2: Pink (Ignition 1 Voltage)
The pink wire carries ignition 1 voltage, which is supplied by the ignition switch when it is turned to the ON position. This wire provides power to various components, such as the ignition coil, fuel pump, and engine control module.
Wire 3: Yellow (Accessory Voltage)
The yellow wire supplies accessory voltage when the ignition switch is turned to the ACC position. This voltage is used to power accessories like the radio, power windows, and interior lights.
Wire 4: Black/White (Ground)
The black/white wire serves as a ground connection for the ignition switch. It ensures a proper grounding path for the electrical system, preventing any electrical malfunctions.
Wire 5: Black (Ground)
Similar to the black/white wire, the black wire also functions as a ground connection. It provides an additional grounding path for the ignition switch and other electrical components.
Wire 6: White (Powertrain Control Module)
The white wire connects the ignition switch to the powertrain control module (PCM). It carries crucial signals and commands between the ignition switch and the PCM, allowing the engine to start and run smoothly.
