HOW TO USE:

1. Mount the Gauge: Locate a suitable 3.3″ (84mm) diameter opening in your dashboard or instrument panel. Insert the tachometer into the opening from the front. Secure it from the back using the included gauge mounting ring.
2. Connect the Power and Lighting Harness: Attach the 3 ft power and lighting harness to the appropriate terminals on the back of the tachometer. Connect the power wire (typically red) to a 12V power source that is switched with the ignition. Connect the ground wire (typically black) to a reliable ground point on the vehicle chassis. If the gauge has a separate lighting wire (often orange or yellow), connect it to your vehicle’s lighting circuit so the gauge illuminates with your other lights.
3. Connect the Tachometer Signal Harness: Attach the 8 ft tachometer harness to the designated signal terminal on the back of the tachometer. Connect the other end of the signal wire to a reliable tachometer signal source. This is typically the negative (-) side of the ignition coil on vehicles with standard spark plug ignition systems. Consult your vehicle’s wiring diagram if you are unsure of the correct connection point.
4. Test the Gauge: Once all connections are secure, start your vehicle’s engine. The tachometer needle should rise and indicate the engine’s RPM. Verify that the LED lighting functions correctly when the vehicle’s lights are turned on.
5. Secure Wiring: Ensure all wiring is routed safely, away from moving parts and heat sources, and is properly secured to prevent accidental disconnection.
