ABS Module Part # differences

[Shadow351]

I'm looking at replacing the ABS Module on my 2010 SHO to hopefully fix my sinking brake pedal. Ford wants almost $1800 for a new one so that is not an option, and even the $600 or so non Ford, remanufactured units are out of my budget, so I have been looking on eBay for used units.

The part number on the module in my car is AG13-2C405-AE. This part number is difficult to find, and when I do, they are $100+ with unknown mileage on them.
I have found a few BG13-2C405 for around $50 with <100k miles on them (B in the prefix denotes a 2011 model year part)
I have found a seller that has a AA53-2C405-BE for $65 with supposedly 85k on it out of a 2010 Taurus (even though AA53 is a Lincoln part number
and a BG13-2C405 also for $65 with supposedly 58k on it out of a 2011 MKS (even though it has a Taurus part number)

Does anyone know what the difference between these modules are? Are they interchangeable? I was able to extract the configuration out of the module in my car, so I should be able to "program" the replacement module if it is compatible.

Thanks

Parts Cannon fired...and it seems to be a miss, Found an AG13-2C405-AE that was supposedly off a 2010 MKS with 40k miles but after bleeding the system (including the ABS service bleed in the scan tool), my sinking pedal is still present. Master cylinder seems to be OK per the "bypass test" in the service manual, what else could cause a sinking pedal?

Did you check the master cylinder AFTER the abs bleed, or BEFORE? Could it be the ABS needs to be bled again? Wouldn't be the first time. Otherwise the MC is leaking into the booster, which I have seen posted about on the SHO, or there is a fluid leak.
