1. Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of your Dakota Digital VFD3-VW-Z Gauge Instrument System. This system is designed to offer advanced digital instrumentation for 1958-1977 Volkswagen Beetle vehicles, featuring high-brightness vacuum fluorescent displays for accuracy and reliability.

Please read this manual thoroughly before installation and operation to ensure proper function and to maximize the lifespan of your instrument system.

2. Product Overview

Image: The Dakota Digital VFD3-VW-Z Gauge Instrument System, featuring three distinct panels. The left panel displays RPM and oil pressure/temperature. The center panel shows MPH and odometer. The right panel indicates fuel percentage and volts. All displays are digital with a brushed aluminum bezel.

The Dakota Digital VFD3-VW-Z system is a full 6-gauge instrument system housed within billet aluminum bezels. It integrates essential vehicle information into a modern, digital format. Due to the air-cooled engine design of the compatible vehicles, this system includes an oil temperature gauge instead of a water temperature gauge.
