Hi im currently in the process of switching put my factory 2004 saturn vue stereo head unit and putting in a touch screen. There is a wire that slides on to the old unit via a metal tab. Does anyone know what this is for?? The new touch screen does not have this metal tab and i had it installed and it was working but didnt leave it hooked up because of this. I have some pictures of said wire.
