Speedhut 4″ 12K Tachometer/120 mph GPS Speedometer Gauge (R4-DS13-REV)

Description

The Speedhut 4″ 12K Tachometer/120 mph GPS Speedometer Gauge (R4-DS13-REV) offers a convenient and accurate way to monitor two critical vehicle parameters in a single, compact unit. This 4-inch gauge combines a high-resolution tachometer capable of reading up to 12,000 RPM with a precise GPS-based speedometer that measures speeds up to 120 MPH. Utilizing GPS technology for speed measurement eliminates the complexities of traditional speed sensors and ensures accuracy regardless of tire size or drivetrain modifications. Designed for ease of installation, this dual gauge is a valuable addition to any vehicle where precise engine and speed monitoring are essential.

KEY FEATURES AND BENEFITS:

• Dual-function gauge: Provides real-time readings of engine revolutions per minute (RPM) and vehicle speed using GPS.
• Wide RPM range: Tachometer reads up to 12,000 RPM, suitable for everyday drivers to high-performance engines.
• Accurate GPS speedometer: Measures speeds up to 120 MPH without mechanical or electronic speed sensors.
• Easy installation: Simplifies setup by eliminating speed sensor wiring and calibration.
• Standard size: 4-inch diameter fits many standard gauge mounting locations.
• Complete kit: Includes wiring harnesses and GPS antenna for straightforward installation.

SPECIFICATIONS:

• Gauge Type: Dual GPS Speedometer
• Tachometer Range: 0 – 12,000 RPM
• Speedometer Range: 0 – 120 MPH
• Size: 4 inches (diameter)
• Mounting Hole Size: 3.93 inches (100mm)
• Units: Standard (MPH)
• Included:
  • 3 ft Power & Lighting Harness – for LED Lit Gauges and Clocks
  • GPS Antenna with 9.8 ft cable and male SMA connector
  • 8 ft Tachometer Harness – for LED Lit Gauges (1 Wire 2 Pin Connector)

HOW TO USE:

1. Mount the Gauge: Secure the 4-inch gauge into a 3.93-inch (100mm) diameter mounting hole in your desired location.
2. Connect Power and Lighting: Attach the 3 ft Power & Lighting Harness to the gauge. Connect the power wire to a 12V switched power source, the ground wire to a suitable ground, and the lighting wire to your vehicle’s lighting circuit if illumination with your lights is desired.
3. Connect the Tachometer: Connect the 8 ft Tachometer Harness to the designated terminals on the gauge. Connect the single wire to a suitable tachometer signal source (e.g., ignition coil negative, ECU tach output, or inductive pickup). Consult your vehicle’s service manual for the correct location.
4. Install the GPS Antenna: Mount the GPS antenna where it has a clear, unobstructed view of the sky. Ensure the 9.8 ft cable can reach the gauge unit. Connect the male SMA connector to the gauge.
5. Initial Power-Up: Turn on the vehicle ignition. The gauge will power on, the speedometer will acquire a GPS signal (which may take a few moments), and the tachometer will display engine RPM when running.
