HOW TO USE:

1. Mount the Gauge: Choose a suitable location on your dashboard and drill a 3.95-inch (100mm) diameter hole. Insert the Speedhut 4″ Tachometer into the hole and secure it using the included gauge mounting ring.
2. Connect the Power and Lighting Harness: Connect the 3 ft Power & Lighting Harness. Typically, this will involve connecting a wire to a 12V power source (ignition switched is recommended), a ground wire to a suitable grounding point on the vehicle chassis, and potentially a wire to your vehicle’s lighting system if you desire the gauge to illuminate with your headlights.
3. Connect the Tachometer Signal Harness: Connect the 8 ft Tachometer Harness. This wire needs to be connected to the tachometer signal output from your vehicle’s ignition system. The exact wire and location will vary depending on your vehicle’s make and model. Consult your vehicle’s service manual or a reliable wiring diagram for the correct connection point.
4. Calibrate (if necessary): Depending on your engine type (number of cylinders), you may need to calibrate the tachometer. Refer to the Speedhut documentation for instructions on setting the pulses per revolution to match your engine (1/2 pulse to 6 pulses per rev).
5. Set the Shift Light: If desired, set the RPM at which you want the shift light to activate. This process will be detailed in the Speedhut documentation and usually involves adjusting a setting on the gauge itself.
6. Test the Operation: Start your vehicle and observe the tachometer readings. Ensure the RPM is displayed accurately and that the shift light activates at the set RPM.
