This 2-1/16" analog-style coolant temperature gauge is built specifically for Holley EFI systems and is compatible with Terminator, HP, and Dominator ECUs. CAN-bus communication lets it daisy-chain with other Holley EFI CAN gauges using the included stereo cables, and a plug-and-play gauge module handles all ECU communication through a single wire.
