The display is clearly analog, but at it's heart this is a precision digital device. Leave it to Holley to combine the best of both worlds into this amazing analog display gauge driven through their digital CAN bus. Check out these features:

• Plug and play compatibility with all Terminator, HP, and Dominator ECU
• Requires no programming. Just connect to ECU with plug-in data bus cable.
• Uses existing sensors connected to Holley ECU--No need to add new sensors
• Easy to read! Back face, silver lettering, and brigh red pointer with 270° sweep from 6- to 3-o'clock
• Designed for the track, the pointer remains steady even in tough track conditions
• LED Warning Light can be programmed to provide both low and high warning levels and configured for day or nighttime use

Note! The first Holley Analog-Display gauge you install requires the installation of a 554-130 CAN Bus Module, available separately. All gauges installed after this can be connected to the first with the included 6-inch Daisy Chain cable
