Holley Water/Methanol injection solenoids (PN’s 557-103, 557-105, & 557-106) are required to be driven by an injector driver output. If an extra is not available on your HP or Dominator ECU, this module can be used and driven by one of the Pulse Width Modulated outputs (either “PWM+” or “PWM-“). This module can be used to drive two solenoids, one on each output channel.
