That’s only the software, you need the firmware upgrade to MY18.5+. At a minimum to this level…
3.2/3.3 APIM NAV & NON-NAV Unit Firmware (Production Release, 2018.5, Late J thru K Series)
Secondary Boot Loader: GB5T-14G376-AA
Strategy (F188): 1U5T-14G374-DA (6/27/2018)
Calibration (F124): 1U5T-14G375-DA (NAV) / 1U5T-14G375-CA (NON-NAV)
ECU Configuration/Sound Profiles (F10A): GB5T-14G379-AA
ECU Configuration/Illumination Strategy (F16B): JB5T-14G379-BA (6/7/2018)
You will also need an asbuilt from a similar Mustang for the TCU. That asbuilt is for the Ecosport and is not the same.
