The Holley Dominator and Terminator X Max ECU’s have built-in capability to control the Drive-By-Wire throttle pedals and throttle bodies used on most 2018-2022 Ford Coyote and 2020-2022 Ford Godzilla applications. To ensure a safe and reliable installation, there are certain hardware requirements that must be followed: Golden Rule: These are plug-and-play harnesses. If they don’t plug, don’t play. Only the factory drive-by-wire throttle body has been pre-calibrated and approved for use with these harnesses. Some applications have different connectors, have not been tested, and are therefore not approved for use with the Holley ECU. The 558-469 DBW harness is made for compatibility with the stock pedal assembly. The following pedal part numbers are compatible: BR3Z-9F836-D, BR3Z-9F836-C, and CR33-9F836-BA. This harness is made for compatibility with the stock throttle body assembly (Part number: JL3E-9F991-AA). Earlier software versions will not have this part number listed in the throttle body type. However, it is acceptable to use the “Ford PN M9926-M52/FR3E-9F991- AA (15-17 Coyote)” Throttle Body option if “Ford PN M9926-M52/FR3E-9F991-AA/JL3E-9F991-AA (15-22 Coyote/Godzilla)” is not an option in your version of software.
