Holley EFI Four Channel Coil Driver Module 554-112

Used to drive a two wire ?
The four channel coil driver module is used to drive a two wire "dumb" ignition coil. Such coils are typically used on Ford Modular and late model Chrysler HEMI engines. Holley EFI ECUs require this coil driver module when running two wire "dumb" coils. Each module can drive four coils, so two are required for an eight cylinder engine that uses eight coils.
Included is the coil driver module, an input harness with pins that can be connected directly into the HP or Dominator ECU, and an output harness with pigtail ends. The user must connect these to their specific coils.FeaturesDesigned for GM LS Gen III and IV engines equipped with GM LS3/L92 cylinder headsProvides best performance for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm, depending on the applicationDual-injector, separate-passage, high-volume fuel rails with mounting hardware, dual-fuel capable, 8 AN o-ring ports Modular LS3 Lo-Ram design allows customization for user desired configurationsModular design allowing the use of the included top-feed plenum entryAvailable with both as-cast satin and black power-coat finishesHigh volume fuel rails for eight and sixteen injector configurations.
