• Integrated Warning Light: Features a built-in warning light that can be configured to alert you when the air/fuel ratio falls outside of a safe or desired range.
• Standard Size: The 2 5/8 inch (66.675 mm) gauge size fits common aftermarket gauge pods and mounting solutions.
• Easy Installation: Designed for a 2.67 inch (68mm) mounting hole, simplifying the installation process.
• Included Wiring Harnesses: Ships with necessary harnesses for power, lighting, and signal connections.

SPECIFICATIONS:

• Gauge Type: Air/Fuel Wideband Gauge
• Range: 10 – 18 AFR
• Size: 2 5/8 inch (66.675 mm)
• Hole Size: 2.67 inches (68 mm)
• Input Voltage: 0 volts to 4 volts
• Warning Light: Yes
• Ships With:
• 8 ft Tachometer Harness – for LED Lit Gauges (1 Wire 2 Pin Connector)
• 3 ft Power & Lighting Harness – for LED Lit Gauges and Clocks
• AF/WB Throttle Position Harness (LED Lite Gauges)

HOW TO USE:

1. Mount the Gauge: Locate a suitable 2.67 inch (68mm) opening in your desired location (e.g., gauge pod, dashboard). Secure the gauge in the opening.
2. Connect the Wiring Harnesses:
   • Connect the 3 ft Power & Lighting Harness to a suitable power source (typically 12V switched ignition) and ground. This harness also provides power for the gauge’s illumination.
   • Connect the 8 ft Tachometer Harness (likely used for illumination power) as needed.
   • Connect the AF/WB Throttle Position Harness according to the instructions for your specific PLX Devices controller and oxygen sensor. This harness will carry the air/fuel ratio signal to the gauge.
3. Connect to PLX Devices Controller: Ensure the gauge’s signal wire from the AF/WB Throttle Position Harness is correctly connected to the output of your PLX Devices wideband controller.
4. Configure Warning Light (if applicable): Follow the gauge’s or PLX controller’s instructions to set the desired air/fuel ratio thresholds for the warning light to activate.
5. Power On and Monitor: Once all connections are secure, power on your vehicle. The gauge should illuminate and display the current air/fuel ratio. Monitor the readings to ensure your engine is operating within the optimal range.
