The Holley EFI CAN Input-Output Module Kit boosts the functionality of the Holley EFI HP, Dominator, Terminator X, or Terminator X Max EFI. This kit enhances the input and output control of the ECU through eight additional inputs and outputs. The module lets you effectively control more functions or monitor more data channels.

With this kit, you can utilize new input channels for the brake pedal switch, fuel pressure sensors, oil pressure sensors, coolant temperature sensors, and many others. You can also use these new output channels for relay control, PWM fuel pump control, or other PWM-controlled devices. With a pre-terminated CAN Harness and pre-terminated flying leads included in the kit, Holley ensures the quick and easy installation of the Holley EFI CAN module to an existing Holley EFI system. If you've already maxed out your ECU's input and output channels, the Holley EFI CAN Input-Output Module Kit is a superior solution to improve the ECU's capabilities.
