Holley 2-Channel Peak and Hold Water/Methanol Injection Driver Module

High Current Water Methanol Solenoid Driver

Features & Benefits
Includes all necessary electrical connectors

Fits: High Current Peak and Hold

Installation note: Holley Water/Methanol injection solenoids (Holley P/N’s 557-103, 557-105, and 557-106) are required to be driven by an injector driver output. If an extra is not available on your Dominator or HP 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. The grey wire is used to determine if the trigger is a ground PWM output or a +12V PWM output (see wiring below).
