SPECIFICATIONS:

• Gauge Type: Dual GPS Speedometer / Tachometer
• Speedometer Range: 0-160 MPH
• Tachometer Range: 0-8,000 RPM
• Gauge Size: 4-1/2 inch (4.5")
• Mounting Hole Size: 4.250 inches (108mm)
• Standard or Metric: Standard (MPH)
• Included:
  • 3 ft Power & Lighting Harness - for LED Lit Gauges and Clocks
  • GPS Antenna with 9.8 ft long cable and male SMA connector
  • Wiring Harness (2-Wire Cable)

HOW TO USE:

1. Mount the Gauge: Locate a suitable 4.250" (108mm) diameter hole on your dashboard or mounting panel. Insert the gauge into the hole from the front. Secure the gauge from the back using the provided spin-lock ring by twisting it until the gauge is firmly held in place.
2. Connect the Power Harness: Connect the 3 ft Power & Lighting Harness to the designated terminals on the back of the gauge. Ensure the positive (12V) and negative (ground) wires are correctly connected to your vehicle's electrical system. This harness also provides power for any LED illumination features of the gauge.
3. Install the GPS Antenna: Choose a location for the GPS antenna that offers a clear line of sight to the sky. The antenna is waterproof and can be mounted externally or internally (ensure no significant obstruction like a metal roof). Connect the GPS antenna to the gauge using the 9.8 ft cable with the male SMA connector.
4. Connect the Tachometer Harness: Connect the 2-Wire Wiring Harness to the tachometer signal output from your engine's ignition system or ECU (Engine Control Unit). Consult your vehicle's service manual to identify the correct tachometer signal wire. Connect the other end of the harness to the designated terminals on the back of the gauge.
5. Power On: Once all connections are secure, turn on your vehicle's ignition. The gauge should power up. The GPS speedometer will begin acquiring a satellite signal, which typically takes a few seconds. Once a signal is acquired, the speedometer will display your current speed. The tachometer will display the engine's RPM based on the signal it receives.
