HOW TO USE:
- Mount the Gauge: Locate a suitable 4.23″ (108mm) diameter hole in your dashboard or instrument panel. Insert the gauge into the hole and secure it using the spin-lock ring from the back.
- Connect Power: Connect the 3 ft Power & Lighting Harness. Typically, this involves connecting the power wire to a 12V source in your vehicle, the ground wire to a suitable ground point, and the lighting wire to your vehicle’s lighting circuit if you want the gauge to illuminate with your other lights.
- Install the GPS Antenna: Choose a location for the GPS antenna that has a clear view of the sky, such as the roof or the top of the dashboard. Clean the mounting surface and secure the antenna.
- Connect the GPS Antenna: Route the 9.8 ft cable from the GPS antenna to the back of the speedometer gauge and connect the male SMA connector to the corresponding port on the gauge.
- Connect the Tachometer Signal: Connect the 3 ft Wiring Harness (2-Wire Cable) to the tachometer signal output from your engine’s control unit or ignition system. Consult your vehicle’s service manual for the location of the tachometer signal wire. Connect the other end of the harness to the designated terminals on the back of the Speedhut gauge.
- Verify Functionality: Once all connections are made, start your vehicle and observe the gauge. The speedometer should begin registering your speed as you move, and the tachometer should display the engine’s RPM.
