HOW TO USE:

1. Prepare the Mounting Location: Choose a suitable flat surface on your vehicle’s dashboard where the 4.250-inch (108mm) diameter hole can be made.
2. Create the Mounting Hole: Carefully cut a 4.250-inch (108mm) diameter hole in the chosen location.
3. Position the Tachometer: Insert the Speedhut tachometer into the newly created hole in the dashboard.
4. Secure with Mounting Ring: From the back of the dashboard, slide the included gauge mounting ring over the back of the tachometer and tighten it to secure the gauge firmly in place.
5. Connect the Power Harness: Connect the 3 ft Power & Lighting Harness. Typically, this involves connecting the power wire to a switched +12V source, the ground wire to a suitable ground point, and the lighting wire to your vehicle’s dashboard lighting circuit (if desired for illumination).
6. Connect the Tachometer Signal Harness: Connect the 8 ft Tachometer Harness to the tachometer. The other end of this harness needs to be connected to the tachometer signal source in your vehicle’s engine. This is typically the negative (-) side of the ignition coil or a designated tachometer output from your engine control unit (ECU), depending on your vehicle’s specific wiring.
7. Final Checks and Testing: Once all connections are made, carefully check all wiring to ensure secure and correct connections. Reconnect your vehicle’s battery and start the engine to test the tachometer’s functionality and the shift light. You may need to calibrate the tachometer for the correct number of cylinders if it doesn’t read accurately initially (refer to your vehicle’s service manual for the correct setting).
