Guys, you'll need a factory wiring diagram for your year before trying to make a swap like this. I don't know for sure how much the wiring has changed, but from what I can see (I have 2009 and 2017 manuals), it's pretty similar overall.
First, you must have memory seats in order to install memory mirrors. There's no practical way to add a memory option (not saying it's impossible, just impractical). If you have memory already and want to add power-fold and auto-dim options, you must first verify that your year had a power-fold option available. If yes, then you need to swap out your power mirror switch and run some new wires to the Driver Seat Module (DSM). The DSM drives the mirror folding motors using input from the mirror switch.
If your year did not offer power-fold as an option, you can still add it but it will require some custom wiring such as adding a relay or using an aftermarket module to drive the mirror folding motors.
Again, the DSM controls the folding motors. A brief 12V pulse from the mirror switch triggers the module to fold/unfold the mirrors. The module "knows" how long to move the mirrors so they end up in the right position. One disadvantage to using a relay or aftermarket module is you might "over drive" the mirrors past their limits. This will still work, but it could cause added wear and tear on the folding motors.
The auto-dim function is controlled by the interior rearview mirror. If an auto-dim outside mirror was not an available option for your year, the interior rearview mirror might not have the additional output to drive it. In that case, it should be possible to swap your interior rearview mirror with a newer one that has the extra output to drive the auto-dimming driver's side mirror.
Hope that helps!
