The Autometer Sport Comp Tach, a popular choice among performance-driven drivers, is known for its accuracy and responsiveness. However, even the most reliable instruments can require attention. Understanding the wiring diagram is crucial not only for troubleshooting but also for customizing the tachometer’s features, such as setting the redline or adjusting the illumination. Let’s embark on a journey of understanding the intricate world of Autometer Sport Comp Tach wiring.
Decoding the Autometer Sport Comp Tach Wiring Diagram
Understanding the Basics
The wiring diagram, essentially a schematic representation of the tachometer’s internal connections, plays a vital role in ensuring proper functionality. It reveals the intricate pathways through which electrical signals flow from the vehicle’s engine to the tachometer, enabling it to display the engine’s revolutions per minute (RPM). The diagram typically presents the tachometer’s terminals, each assigned a specific function and labeled accordingly. It also shows the corresponding color-coded wires that connect to each terminal, making it easier to identify and trace each wire’s pathway.
Essential Components of the Wiring Diagram
Let’s break down the key elements of the Autometer Sport Comp Tach wiring diagram. The diagram usually includes:
- Power Supply: The tachometer’s power supply is indicated by a designated terminal (often labeled “PWR”) and the corresponding wire that connects to the vehicle’s ignition system. This connection ensures that the tach receives power only when the ignition is turned on.
- Signal Input: The tachometer receives a pulsing signal from the vehicle’s engine. The signal input terminal is usually marked “SIG” or “IGN.” This terminal is connected to a wire that taps into the engine’s ignition system, typically the coil or the distributor.
- Ground: All electrical devices need a solid ground connection. The wiring diagram will show a terminal labeled “GND” or “GRD” and the associated wire that connects to the chassis or a negative terminal of the vehicle’s battery.
- Illumination: The tachometer’s illumination is controlled by a separate circuit, often powered by the vehicle’s parking light system. This connection is displayed on the diagram with a terminal labeled “ILL” or “DIM” and the corresponding wire that connects to the parking light circuit.

Visualizing the Connections
While the wiring diagram provides a comprehensive overview, it’s essential to physically trace the wires and confirm their connections. The diagram will guide you to the correct terminals, but it’s always a good idea to double-check the connections to ensure they match the diagram. Look for color coding, insulation markings or labels that can assist in identifying and verifying the wires.
Troubleshooting with the Wiring Diagram
Troubleshooting a malfunctioning tachometer starts with understanding the wiring diagram. If the tachometer is not functioning, check the connections at each terminal. Make sure the power supply wire is connected and receiving power, and verify that the signal input wire is properly connected to the engine’s ignition system. Also, ensure the ground connection is secure, and that the illumination wire is connected to the parking light circuit. By comparing your actual wiring to the diagram, you can quickly trace and isolate any issues.
Customization with the Autometer Sport Comp Tach Wiring Diagram
Beyond troubleshooting, the wiring diagram unlocks a realm of customization possibilities. By understanding the wiring, you can fine-tune the tachometer’s performance and appearance to match your preferences.
- Redline Adjustment: Some Autometer Sport Comp Tach models offer a redline adjustment feature. The diagram will specify a terminal that allows you to connect a resistor to change the redline setting. By using different resistor values, you can customize the tachometer to display different redline levels.
- Illumination Color: Many models include customizable illumination features. By understanding the wiring, you can replace the stock bulb with a different color to accentuate your dashboard. The wiring diagram will detail the correct terminal and bulb specifications to maintain proper functionality.
- Additional Features: Some Autometer Sport Comp Tach models may have other adjustable features, such as peak recall or a warning light. The wiring diagram will provide detailed instructions for connecting and configuring these features.
Using the wiring diagram as a guide, you can safely and effectively customize your Autometer Sport Comp Tach to enhance its functionality and aesthetics.
