Speedhut Speedbox w/VW Clip-on Cable (A-373)

Description

The Speedhut Speedbox w/VW Clip-on Cable (A-373) offers a seamless solution for integrating modern speed-sensing technology with your classic Volkswagen’s mechanical speedometer. This innovative converter allows you to drive your original gauge using either a precise GPS signal or a modern Vehicle Speed Sensor (VSS) input, providing accurate and reliable speed readings. Designed for ease of installation, it requires minimal wiring and comes complete with a specific “clip-on” style mechanical drive cable tailored for Volkswagen speedometers. Whether you’re upgrading your vintage ride or tackling a custom build, the Speedhut Speedbox A-373 ensures your original speedometer remains functional and accurate in the digital age.

KEY FEATURES AND BENEFITS:

• GPS and VSS Compatibility: Operates your mechanical speedometer using either a Global Positioning System signal for pinpoint accuracy or a Vehicle Speed Sensor signal from your transmission.
• Direct Fit for VW: Includes a 3-foot mechanical drive cable with a specialized “clip-on” connector designed for direct attachment to Volkswagen speedometers, simplifying the installation process.
• Simple Installation: Requires only a 12-volt power and ground connection, making it a straightforward upgrade without complex wiring or extensive modifications.
• Automatic GPS Calibration: When utilizing the GPS input, the Speedbox automatically calibrates for accurate speed readings without the need for manual adjustments or subscription fees.
• Wide Calibration Range: Offers an adjustable calibration range from 170 to 1650 turns per mile, accommodating various speedometer types and ensuring accurate display.
• Compact and Versatile Mounting: The unit’s small form factor allows for flexible mounting options within the dashboard or engine bay.
• Complete Package: Comes with the Speedbox unit, GPS antenna, power harness, and the 3-foot VW clip-on speedometer cable, providing everything needed for installation.

SPECIFICATIONS:

• Brand: Speedhut
• Part Number: A-373
• Drive Output Thread: 7/8″-18
• Drive Output Square: 0.112″
• Calibration Range: 170 – 1650 turns per mile
• Default Calibration: 1000 turns per mile (for US speedometers)
• Included: Speedbox unit, GPS antenna, power harness, 3-foot VW clip-on speedometer cable.

HOW TO USE:

• Begin by disconnecting the negative terminal of your vehicle’s battery for safety.
• Connect the “clip-on” end of the provided 3-foot mechanical speedometer cable to the back of your Volkswagen mechanical speedometer. Ensure a secure connection.
• Carefully route the other end of the speedometer cable to your desired mounting location for the Speedbox unit. Avoid any sharp bends or kinks in the cable.
• Mount the Speedbox unit in a suitable location, such as under the dashboard or on the firewall in the engine bay. Ensure it is protected from direct water exposure.
• Plug the included wiring harness into the connector on the back of the Speedbox. Connect the red wire to a 12-volt power source and the black wire to a suitable ground.
• Connect the GPS antenna to the designated port on the Speedbox. For optimal GPS signal reception, mount the antenna with a clear view of the sky, preferably with the magnetic side facing down. It can typically receive signals through non-metallic materials.
• Reconnect the negative terminal of your vehicle’s battery.
• If you intend to use a Vehicle Speed Sensor (VSS) signal instead of or in addition to GPS, connect the VSS output wire from your vehicle’s transmission to the appropriate wire on the Speedbox wiring harness (refer to the Speedhut documentation for specific wiring). Initial calibration using the GPS signal is recommended for VSS setup. Drive the vehicle above 25 MPH briefly with the GPS connected to allow the VSS signal to be learned.

BENEFITS OF USING THE SPEEDHUT SPEEDBOX W/VW CLIP-ON CABLE (A-373):

• Preserves Original Aesthetics: Allows you to retain the classic look and feel of your Volkswagen’s original mechanical speedometer while benefiting from modern speed-sensing technology.
• Ensures Accurate Speed Readings: Provides precise speed information derived from either GPS satellites or your vehicle’s speed sensor, eliminating inaccuracies associated with worn or mismatched mechanical components.
