I have premium package, no rear camera - thinking about putting one in though. That is why I need to know what the wires are for. Thanks.

 

Those wires are for the auto dimming function in the mirror at night.

 

Thanks! So - is there a mirror I can get that will utilize the auto dimming AND give me a monitor for the camera? Or am I stuck manually dimming - not the end of the world...?

 

Here's one:

yikes, $700 for the mirror?! even with the connector and harness, that is expensive.

search around this forum, you will see plenty of people that did the conversion (myself included). it is not for the faint of heart.

the OEM mirrors are the same as the F150 mirrors and you can find hem on fleabay for $300 or less. you also have to get a different connector to make it work). do your research and decide if you rather do this or an aftermarket nav system with rear backup.

 

And there's already the "reverse" wire there, even if you don't have the camera, because mirror auto-dimming is switched off when in reverse.

Actually, in the Premium there are no wires in the main connector for auto-dimming per se, since the sensor is built in to the mirror. For 2013 at least.
