Disconnect the negative battery cable: Ensure the vehicle's electrical system is completely powered down for safety.
Choose a mounting location: Select a suitable and visible location on your dashboard or instrument panel for the tachometer.
Prepare the mounting hole: If necessary, create a 3.3-inch (84mm) diameter hole for the gauge to fit.
Connect the wiring:
Connect the power wire (typically red) to a switched 12V power source.
Connect the ground wire (typically black) to a solid ground point on the vehicle's chassis.
Connect the tachometer signal wire (often yellow or green) to the appropriate signal source (negative coil terminal, coil trigger wire, or ECU tach output, depending on your vehicle's ignition system).
Connect the illumination wire (if present) to the vehicle's lighting circuit so the gauge lights up with your other instruments.
Mount the gauge: Insert the tachometer into the mounting hole and secure it using the included gauge mounting ring from the back.
Reconnect the negative battery cable: Once all wiring is securely connected, reconnect the vehicle's negative battery cable.
Program the Pulses Per Revolution (PPR): Following the manufacturer's instructions (usually involving pressing a button during power-up), set the correct PPR for your engine's cylinder configuration. Refer to the Speedhut documentation for the appropriate PPR setting for your specific engine.
Test the gauge: Start your engine and observe the tachometer to ensure it is reading the RPM accurately.
