HOW TO USE:

1. Preparation: Identify a suitable location on your dashboard with a 3.3 inch (84mm) diameter opening. Ensure there is adequate space behind the dashboard for the gauge and wiring.
2. Mounting the Gauge: Insert the Speedhut 3-3/8″ Tachometer into the 3.3 inch (84mm) hole. Secure it from the rear using the provided gauge mounting ring. Tighten the ring until the gauge is firmly in place.
3. Connecting the Power and Lighting Harness: Connect the 3 ft Power & Lighting Harness to the appropriate power and ground sources in your vehicle’s electrical system. This harness will also power the LED illumination of the gauge. Refer to your vehicle’s wiring diagram for correct connections.
4. Connecting the Tachometer Signal Harness: Connect the 8 ft Tachometer Harness to the tachometer signal output from your engine’s ignition system. Typically, this involves connecting to the negative (-) side of the ignition coil or a designated tachometer output wire from your vehicle’s ECU (Engine Control Unit). Consult your vehicle’s service manual for the precise location of the tachometer signal wire. The harness uses a 1-wire, 2-pin connector to interface with the gauge.
5. Testing: Once all connections are made, start your vehicle’s engine. Observe the tachometer to ensure it is receiving a signal and displaying the correct RPM. Verify that the LED illumination is functioning when the vehicle’s lights are turned on.
