HOW TO USE:

1. Preparation: Disconnect the vehicle’s negative battery terminal for safety.
2. Mounting: Locate a suitable 4.250" (108mm) diameter opening on your dashboard. Insert the tachometer into the opening from the front. Secure it from the back using the provided gauge mounting ring.
3. Wiring – Power and Lighting: Connect the 3 ft power & lighting harness. Typically, this involves connecting a wire to a 12V accessory power source (switched with the ignition), a wire to ground, and a wire to your vehicle’s lighting circuit (for illumination when headlights are on). Refer to the specific wiring diagram included with the product.
4. Wiring – Tachometer Signal: Connect the 8 ft tachometer harness (single wire) to the tachometer signal source in your vehicle. This connection point depends on your ignition system type (e.g., negative coil terminal on older systems, a specific trigger wire on coil packs or coil-on-plug systems, or the designated tach output from the ECU). Consult your vehicle’s service manual for the correct tachometer signal wire location.
5. Final Steps: Once all wiring is complete and secure, carefully reconnect the vehicle’s negative battery terminal. Start your engine to verify the tachometer is functioning correctly and displaying the engine’s RPM. Calibration for the correct pulses per revolution (PPR) might be necessary based on your engine type; refer to the Speedhut instructions for this process.
