more than likely you have a code that needs to be cleared by ford or aomeone with a scanner. The bags were never deployed right just a seat change
Have you taken the car to a mechanic that can read Air bag codes? If not you should then they can tell you exactly what's causing it.
Do the recaro seats have the air bladder in the passenger seat like the gt seat?
If you swapped in the 2013 airbags, then the only remaining difference is the occupant classification system in the passenger seat. Other than that, I can't think of anything different about the seats. I disassembled my 401A seats and installed the power tracks, adjustable lumbars, and heating elements into a set of FRPP Recaros, but the Recaros I bought have the correct part number for the 2011-2012 cars. While I left the airbags in place, I did swap the OCS bladder in the passenger seat just out of conservatism.
I hope you're able to get this figured out.
Some research on my end shows that the "Occupant Sensor" (as described on Tousley Parts) is included with the passenger side seat cushion. That is unfortunate, because the cushion (at least the Recaro one) is listed for $691. That's no bueno. You could literally buy a set of used seats for that much money.
Someone has to have one. If you needed an '11/'12 GT one, I could help you myself.
Here's a link to my build thread where I did my power/heated/leather Shelby Recaro swap. It will show you how to swap out the OCS on the passenger side.

There's also an excellent writeup on SVTP by TOB in the GT500 section about doing the Recaro swap that has lots and lots of detailed pictures. It should pick up anything I've not covered.
Let me know if I can help any other way. Good luck with it man.

Awesome. Glad to hear it man. You'll get it all worked out.
Are you going to swap out the cloth for leather while you're at it? It's really not too bad to do, and it will spruce up the interior a bit. (although getting rid of the Recaros is crazy!!)
