Speedhut 3-3/8″ Street XL 8K RPM Shift-light Tachometer (R3-TC3-SXL)

The Speedhut 3-3/8″ Street XL 8K RPM Shift-light Tachometer (R3-TC3-SXL) is an essential instrument for drivers who need precise and immediate feedback on their engine’s performance. This analog gauge is designed to accurately measure engine revolutions per minute (RPM) up to a maximum of 8,000, providing critical data for optimal vehicle operation and performance tuning. Its integrated shift light alerts drivers to ideal gear change points, contributing to improved acceleration and fuel efficiency. Built with quality components and designed for straightforward installation, this tachometer is a valuable addition to any vehicle with a standard spark plug ignition system.

KEY FEATURES AND BENEFITS:

• Accurate RPM Measurement: Provides precise readings of engine speed up to 8,000 RPM, allowing for informed driving decisions and performance monitoring.
• Integrated Shift Light: Features an internal shift light that can be set to illuminate at desired RPM thresholds, signaling the optimal time to shift gears for maximum performance.
• Wide Compatibility: Works seamlessly with most gasoline engines utilizing standard spark plug ignition systems, supporting configurations from 1 to 12 cylinders.
• Standard Size: With a diameter of 3 3/8 inches (85mm), it fits into common 3.3-inch (84mm) dash openings, simplifying installation.
• Complete Installation Kit: Includes a gauge mounting ring and the necessary wiring harnesses (3 ft Power & Lighting Harness and 8 ft Tachometer Harness) for a hassle-free setup.

• Included:
• 3 ft Power & Lighting Harness: for LED Lit Gauges and Clocks
• 8 ft Tachometer Harness: for LED Lit Gauges (1 Wire 2 Pin Connector)
• Gauge Mounting Ring

HOW TO USE:

• Preparation: Identify a suitable 3.3-inch (84mm) diameter location on your vehicle’s dashboard for mounting the tachometer. Ensure there is adequate clearance behind the mounting surface for the gauge and wiring.
• Mounting the Gauge: Insert the Speedhut tachometer into the prepared 3.3-inch (84mm) hole. Secure it from the rear using the included gauge mounting ring. Tighten the ring until the gauge is firmly in place.
• Wiring the Power and Lighting: Connect the 3 ft Power & Lighting Harness. Typically, this involves connecting the power wire to a 12V switched power source in your vehicle, the ground wire to a suitable grounding point, and the lighting wire to your vehicle’s instrument panel lighting circuit if you desire the tachometer to illuminate with your other gauges. Refer to your vehicle’s wiring diagram for specific connections.
• Wiring the Tachometer Signal: Connect the 8 ft Tachometer Harness. The single wire with the 2-pin connector needs to be connected to the tachometer signal output from your vehicle’s ignition system. This is typically found at the negative (-) terminal of the ignition coil on older vehicles or at a designated tachometer output wire on more modern systems. Consult your vehicle’s service manual for the correct wire location.
• Setting the Shift Light (if applicable): Once the tachometer is powered and functioning, you may need to set the desired RPM point for the internal shift light to activate. This process can vary depending on the specific Speedhut model, so refer to the instructions that came with your gauge for detailed steps on shift light adjustment.
• Testing: Start your vehicle and observe the tachometer’s readings as the engine RPM changes. Verify that the shift light illuminates at the set RPM. Ensure all wiring connections are secure and the gauge is functioning correctly.
