HOW TO USE:

• Prepare the Mounting Location: Ensure you have a 3.95-inch (100mm) diameter opening in your dashboard where you intend to mount the tachometer.
• Connect the Power Harness: Connect the 3 ft Power & Lighting Harness. Typically, this involves connecting the power wire to a 12V source that is switched with the ignition, the ground wire to a suitable ground point on the vehicle chassis, and the lighting wire to your instrument panel lighting circuit if you desire the gauge to illuminate with your other gauges.
• Connect the Tachometer Harness: Connect the 8 ft Tachometer Harness to the tachometer signal source. This is usually the negative (-) terminal of the ignition coil or the designated tachometer output wire from your vehicle’s ECU (Engine Control Unit), depending on your specific Datsun Z model and ignition system.
• Mount the Gauge: Insert the tachometer into the prepared dashboard opening and secure it using the included gauge mounting ring.
• Configure the Pulses Per Revolution: Based on your engine type (number of cylinders), you may need to calibrate the tachometer for the correct pulses per revolution. Refer to the Speedhut documentation or your vehicle’s service manual for the correct setting (e.g., a 4-cylinder engine typically uses 2 pulses per revolution). This is usually done via switches or a programming function on the gauge itself.
• Test the Installation: Start your vehicle and verify that the tachometer is reading the engine RPM correctly and that the shift light illuminates at the desired RPM.
