Wiring is that panic-inducing side of hot rodding many of us dread. We often wake from nightmares of loose grounds or faulty connections. Well, Holley knows that pain, and developed Dominator EFI kits, to simplify the installation of the Dominator ECU on popular engine applications.
“This is one part number that a guy can get his car running without having to spec his entire engine,” said EFI Product Manager Colin Kinser. “What used to take us hours on the phone helping find every part number can now be done in just a moment.”
Colin has worked for Holley for several years, starting as a technician helping customers on the phone. “This cuts out hours of tech time or just the simple time of entering all the part numbers,” he says.
Dominator Kits include a Dominator ECU, USB cable, power harness, engine main harness, EV1 injector harness, Bosch Wideband, and ECU mounting hardware.
The Dominator EFI Kit for LS1 (PN 550-650) is an easy installation and includes everything shown with the addition of mounting hardware. The harnesses are designed to be plug-and-play with pre-cut lengths and plenty of flexibility.

One of the biggest draws of a Dominator ECU is the quantity of inputs and outputs, the most in the Holley lineup. This allows racers to handle their entire tune from wheelie control to multiple fuel pumps. It provides more features and benefits then the competition, or other Holley ECUs, such as Terminator X, and HP.
The Dominator uses “Pin Mapping” for inputs and outputs. A strategy that allows inputs and outputs to be pinned as desired by the user with user-programmable caution and warning outputs for all sensors.
The Dominator ECU is fully potted meaning it can be mounted in the engine compartment or interior. Both the power and main engine harnesses feature TechFlex F6 loom which provides protection and a sleek under hood look. The removable sub-harnesses, like coil and injector, provide quick serviceability and customizing.
Of course, fast is never fast enough, but the Dominator EFI Kits are an excellent way to future-proof your build, as Colin calls it. “You build this car with drive-by-wire and trans control and know you’ll likely add another fuel pump in the future, or maybe boost or nitrous control. You can start with the Dominator to future proof the install.”
Dominator EFI Kits will be offered engine-specific, not vehicle-specific, to work in any vehicle application. Generally speaking, kits will be available in multiple configurations such as with and without transmission control harness and drive-by-wire or drive-by-cable.
For those who already have a Dominator ECU on-hand and want to adapt them to their specific application, Holley offers just the harnesses. See the list below:
Of course, the new Dominator plug-and-play harnesses includes applications for LS1 (pictured left) and Ford ’99-’04 Mod-Motors (pictured right). They’re engine specific, not vehicle specific, meaning they’re great for engine swaps too.
For those still wanting more flexibility in their harness, Holley offers several universal options such as the Unterminated Flying Lead Harness pictured left (PN 558-105). These harnesses have at least the Holley ECU-specific plugs, pictured right, with plenty of extra wires for custom applications.
