Hey, I have a 2011 Fiesta SES (For sale!) that has the power auto-dimming rear view mirror. I'd like to bring this along to my new ST. The mounts look the same, but I haven't taken apart the headliner in the ST yet to see if it has the wiring to make the mirror install easy. Has anyone here installed a power mirror in their ST? If I dig around in there is it pre-wired? Thanks!
