You need Ford IDS with a VCM2 (scan tool interface hardware) and you need to perform a PMI (programmable module installation) this is where the software IDS will ask you if the donor used PCM is the vin.. when you choose no it will then ask you if the original vin is correct (obviously you choose yes) then it will connect to the ford server and download the correct calibration based of the vehicles vin. Once the PMI is completed you need to gain security access and perform a parameter reset and then a erase all keys and program 2 keys into the PATS system. The odometer will not be effected by the PCM change.  
   Note: You can also do this with a passthru device.  However using a passthru device to perform vehicle programmings can and sometimes does have pitfalls. There is a number of different passthru devices on the market... some are better then others... some have been validated by manufactures.(tested and tried and meet manufactures criteria) and a bunch have not been validated. When you run into a vehicle that’s doesnt program a pcm or a module or a Key correctly one must consider that the passthru device might be the reason behind this issue. It’s been a documented problem for years. For the locksmiths that are planning to perform additional services like module programming you must considers either purchasing factory scan tool interfaces example (Ford *VCM2, GM *MDI or MDI2, Chrysler *Micropod2 etc etc) or purchasing a J2534 passthru device and perhaps one that has been validated by as many manufactures as possible. 
Tools like the Smart Pro can’t replace a PCM correctly as in this example. 

This is a little video I made this morning while programming a replacement PCM (used) into a 2013 Grand Caravan. Sorry I wasn't too chatty first thing this morning.

I did this using the Maxisys Mini. It showed a failure during the programming cycle, and for some reason it does that frequently since I last updated (it used to do it flawlessly). I find that when it says it failed, all you need to do is hit the "Reset ECU" function and you're good to go. After you finish the programming cycle, make use you run a scan and clear DTC (diagnostic trouble codes).
Now if the customer supplied a brand spanking new PCM, this will NOT work. You need to flash with via J2534.
