Locating Mustang PCM Code by Brenspeed
CPU Code Location
2005 to 2020 Mustang GT CPU code is located in the engine compartment.
When Brenspeed creates a custom tune for your vehicle we need to know
what processor code your car has been assigned by Ford. In the engine
compartment you will find a black rectangular fuse box located on the
passenger side. Next to the fuse box you will find your silver CPU. On
the CPU or the bracket holding the CPU will be a small white sticker.
Printed on this sticker you will find your processor code. It will be 3
letters followed by 1 number.
