Worked for me!
2003 Ford Mustang
Crutchfield Customer Review (What's this?)
This fit my 03 mustang convertible, with Mach 460 sound system. I initially bought the wrong one after watching several online videos, but this is the correct one as advised by the Crutchfield website.
Pros: Correct harness for the job
Cons: One plug was a little loose. Still all works ok though.
