Hi kverden. No, it does not make a difference. In fact, it is common.I have seen a couple part numbers for the FCIM used here. If someone knows what the part number for a 2014 MKS is can you let me know. Does it matter if it is a 2014 but has a manufacture date of 2013 on the door?
In addition, the best way to obtain a correct part number is for the Parts Department at your Lincoln or Ford Dealership (or any other seller/vendor) to use your VIN to properly cross-reference the proper part number.
On a related note…I’m not sure if you’re aware of this, but the FCIM’s for most MyLincoln Touch equipped vehicles are no longer available as new parts. Only refurbished.
Let us know how you make out and good luck.
