HOW TO USE:
- Mount the Gauge: Locate a suitable 2.67″ (68mm) diameter hole in your desired location and securely mount the Speedhut gauge.
- Install the O2 Sensor: Install the included LSU 4.9 wideband O2 sensor into the exhaust system at a location recommended for accurate readings (typically before the catalytic converter and after the exhaust manifolds converge).
- Connect the Wiring Harness: Connect the provided 3 ft power & lighting harness to the gauge and to a suitable power source and ground in your vehicle’s electrical system. Refer to the wiring diagram included with the product for specific connections.
- Connect the O2 Sensor: Connect the LSU 4.9 O2 sensor to the designated connector on the gauge or wiring harness.
- Start Your Vehicle: Once all connections are secure, start your vehicle. The gauge should power on and begin displaying the real-time lambda value.
- Observe Readings: Monitor the air/fuel ratio readings to ensure your engine is operating within the optimal range.
- Heed the Warning Light: If the warning light illuminates, it indicates that the air/fuel ratio has fallen outside the preset safe limits. Investigate the cause promptly.
