No. The only thing ive read in the pats guide is when replacing the pcm you need two keys. As for your part number the only important bits are 7m5t and the first of the two letters after the numbers. The first letter represents options the car is configured for eg cruise control. If you get a D as the first letter its good for everything except st and cc models. So if you get 7M5T xxxxxx Dx where x can be any letter or number it should be good. You then just need a elm327 cable and some free software to write your cars spec to it. If you got a brand new one from ford it would be a model number as above because although they made 100's of varients on the production line they only sell the D type enabled for all as a replacement. As said above though i need confirmation that a second hand unit can be used by someone thats done it as im told by ford only a new virgin unit will work.
