So I recently introduced my 2015 GT to a mailbox and took out the passenger side mirror. Since I'll already have to replace that one, the thought occurred to me to upgrade both mirrors while I'm at it. I have the base GT, but i'd like to possibly upgrade to get the puddle lamps and turn signalling. I dug around a bit, but I can't seem to find any information on whether this would even be possible. Is the wiring for the lamps and the turn signal already included, or does the base have a different wiring harness than the premium? Would it be more of a chore to do this than it's worth?
