Dakota Digital HDX-66C-CVL-K Details

That long, narrow instrument housing doesn’t leave much space for typical aftermarket solutions, but this direct-fit HDX package is anything but typical! Six analog gauge sweeps cuddled up to a large, full-color TFT message center brings your interior into the 21st century without looking out of place. Available with Black or Silver Alloy face styling, this kit is sure to look right at home in your 1966-67 Chevelle, Malibu or El Camino!

Each HDX system allows the user to select independent illumination colors for the gauge readings and needles, as well as the message centers. Calibration and personal settings are manipulated with the built-in, capacitive-touch buttons, or the available Bluetooth app for Apple and Android devices. Each needle hub is black nickel plated spun-aluminum to match the buttons. All HDX instrument systems feature dead-faced indicators (turn signals, high beam, check engine, cruise control, parking brake, plus two user-definable), and a red, settable warning light for each gauge. With our central control box, installation is greatly simplified with vehicle-harness sourced signals and supplied, solid state sending units connecting cleanly to their respective terminal.

*Bezel not included, shown for visual/presentation purposes.

System uses OEM or reproduction style bezel.


Lighting Technology


  • Over 30 user-selectable color options allow you to independently change the needle color, sweep color and digital TFT display color.


  • Both daytime and nighttime brightness can be easily controlled through the HDX setup menu, allowing you to choose your preferred lighting intensity level, toggled by the activation of the headlight switch. If on-the-fly rotary type control is desired, the DIM-1 is a common accessory to add this functionality.


  • With 12 factory preset color themes, you can quickly create a beautiful looking system. Or, for the ultimate in customization, choose all of the color zones yourself.


  • Full LED backlighting provides a strikingly visual gauge package, with sharp contrast for ease of viewing both night and day. Full RBG backlighting allows you to create the specific color you want, with a unique daytime and nighttime theme if desired. Whether your goal is an OE look or something truly bold, the HDX Series lets you make that choice.
