Some 2017-2021 Ford GT vehicles built on or before 22-Sep-2021 may need to have a new battery installed for service or maintenance purposes. A new battery design has been released for service and requires a different battery tray and a different local interconnect network (LIN) connector. This is due to the new battery design being dimensionally smaller and will not properly secure in the original battery tray. The LIN connector socket in the new battery is keyed differently and the original connector shell will not plug in. The LIN connector shell will need to be de-pinned, so the new connector shell can be installed. When installing new battery part number MG7Z-10655-*, the following battery tray and LIN connector must be used: battery tray MG7Z-10732-A, LIN connector shell MG7Z-9A624-A. Refer to Workshop Manual, Section 414-01 for battery tray replacement.
