Holley HP vs Dominator and wiring

Basic overview of the differences between the Holley HP and Dominator ECU. Also some clarity on the wiring harnesses.


Note: All of Holley’s “Terminator” ECUs are in fact either an HP or Dominator. There are zero differences, they are just packaged as a kit which includes wiring harnesses, a small dash, and O2 sensor.


Anyone needing “drive by wire” and/or “electronic transmission control” must use a Dominator ECU.
