Holley EFI 6.86" Pro Dash
When driving your Holley EFI-equipped Mustang, the last thing you have time to do is watch engine vitals. Look no further than Holley EFI's 6.86" Pro Dash! With over 200 monitoring channels, this touch screen dash displays real-time data in an attractive high definition package that will look right at home in your interior. The full-color touch screen makes navigation as easy as using your smartphone (no stylus required)! Utilizing a completely customizable design, this unit has numerous high-end features such as a high contrast 1280x480 resolution screen for the ultimate visibility. Built out of a weather-proof black aluminum housing, this digital dash is the perfect choice for your street or race car. Choose from more than 9 preloaded background skins or plug in your keyboard & mouse to design and import your own design! Featuring a plug & play connection compatible with all Holley EFI management systems, this dash eliminates all guesswork when displaying the most important data coming from your vehicle. The provided 34 pin harness allows 13 multi-configurable inputs that will work with most Holley EFI sensors. Ditch the unnecessary wiring from those inaccurate mechanical gauges for a more precise and customizable dash experience with this digital dash from Holley!

User Defined Warning Lights & Alarms
Protect your investment while keeping your eyes on the road all at the same time by activating the built-in warning light and alarms. Featuring an integrated programmable shift light with ten LEDs in the bezel of the dash, you will never miss a shift again! With an additional 4 LEDs, you can program these to monitor virtually anything (engine vitals, target boost indicator, etc.). This digital dash continually monitors any user-defined values such as fuel & oil pressure to alert potential problems when the parameter is outside of the normal operation. Additionally, this unit can also be programmed to shut down the engine to prevent catastrophic damage before it is too late!

Ease Of Use
To make installation quick and easy, Holley pre-drills mounting holes into the casing and provides a mounting template to speed up the process while eliminating mistakes! Utilizing an easy-to-use virtual switch panel, this dash eliminates the need for dash-mounted switches and even has a built-in GPS module for speedometer and odometer functionality. Forget your laptop? Take control of the on-screen playback feature to view your EFI data logs right from the touch screen. Downloading data logs couldn't be easier as you can save your data logs directly from the dash unit to a micro SD card or memory stick with the built-in external USB port.
