I just got a 2012 Mustang and Crutchfield says that they have no information on them because it's too new and they haven't been able to get a car to inspect. I'm thinking of just running my stock HU and getting an amp integration kit so I don't have to do any splicing, but I don't know if the part for the 2011 will work with the 2012. I asked the salesman at the dealership if anything had changed and he said no but I don't really trust him to know that for sure.
