On the 2012 and earlier trucks the rearview mirror controls dimming the side mirrors. No sales codes were needed. In 2013 and beyond that may have changed. You may also need to add or update the harness that goes to the rearview mirror.
As long as you have remote adjustment on your current mirrors, you should be able to upgrade to the version with turn indicators and puddle lamps. If your current mirrors are 100% manual and you don't have power windows/locks, it involves new wiring and modules in the doors. A dealer will need to input a sales codes for the indicator lamps to work.
I purchased my mirrors from eBay. Nice upgrade for night driving.
