A:Answer Go back to their install department and ask them, They have them all back there. If you are going to tie in the steering wheel controls (GTO like mine has them, not sure on yours) then the interface will be necessary to retain that. Its somewhat complex to wire up if its your first time, but other than that, just follow the directions.
Again, just ask them, they will get it to you. Or you can order specific for vehicle at Crutchfield.
