These analog-style gauges are designed specifically for use with Holley EFI systems. They are compatible with all Terminator, HP, and Dominator ECU's, allowing them to be installed in a variety of Holley EFI equipped vehicles. CAN-bus communication allows the gauges to daisy chain using the included stereo cables, making installation quick and clean. The required gauge module (P/N 554-130) allows plug and play communication between the ECU and gauges, through a one-wire ECU connection.

Can be used with Sniper ECUs when used in conjunction with module part # 554-130.
