Tow mirror upgrade
 

I’m wanting to upgrade my stock mirrors to tow mirrors, on my 2015 XLT.

My stock are heated, and signal, so I want the tow mirrors to do the same, in addition to being power telescoping and power folding.

Can anyone tell me what I need to do besides just buying the door switch control for tow mirrors, and the 8 to 22 pin wire harness? Will I have to replace the module or reflash anything?

Thanks in advance.
