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).\u003c\/p\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":49715274449134,"sku":"HLY-554-115","price":91.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/a25397f145352e05c29aa17299d36a761597e66f.jpg?v=1791567675","url":"https:\/\/elmosspeedshop.com\/products\/holley-efi-holley-2-channel-peak-and-hold-water-methanol-injection-driver-module-554-115","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
