Here's a more detailed description:
* Look for a round, black or gray component with a central cap that has a wire coming out of it. This cap is the distributor cap, and underneath it lies the distributor rotor.
* The distributor is connected to the engine by a drive shaft which rotates the distributor rotor.
* The distributor wires (spark plug wires) will be connected to the distributor cap, leading to each spark plug.
Important Note: This information assumes your Silverado 1500 has a V8 engine. If your truck has a different engine configuration (e.g., V6), the location of the distributor might be slightly different. It's always best to consult your vehicle's repair manual for specific details.
