HOW TO USE:

1. Mount the Speedbox Unit: Choose a secure and accessible location within your vehicle, such as under the dashboard or in the engine bay, ensuring it is protected from extreme temperatures and moisture.
2. Connect Power and Ground: Connect the designated power wire from the Speedbox to a 12-volt power source in your vehicle. Connect the ground wire to a reliable grounding point on the vehicle’s chassis.
3. Connect the Mechanical Cable: Thread the 3/4-20 internal thread end of the included 3-foot mechanical cable onto the back of your early Ford speedometer. Connect the other end of the cable to the drive output of the Speedbox unit.
4. Mount the GPS Antenna (Optional): If you intend to use GPS for speed sensing and automatic calibration, mount the included GPS antenna in a location with a clear view of the sky, typically on the dashboard or roof. Connect the antenna cable to the Speedbox unit.
5. Initial Calibration (GPS): If using GPS, upon initial power-up, the Speedbox will automatically begin calibrating itself using the GPS signal. This process may take a short period.
6. VSS Connection (Optional): If you prefer to use a VSS signal, connect the VSS output wire from your vehicle’s sensor to the designated VSS input wire on the Speedbox unit. You may need to manually calibrate the Speedbox for accurate readings with a VSS signal according to the manufacturer’s instructions.
