I am looking to replace my driver and passenger side mirrors. They are a little beat up and scratched. Just want them to be a little nicer. I don't want aftermarket or tow mirrors or anything like that. However, my 04 Suburban just has the basic power mirrors. No heat. No auto tilt-down in reverse. No auto-dimming. No power-folding. My question is, if I buy a mirror that has all the functionality, is the wiring set up to be plug and play? Or do they just run the wiring for the specific features of whatever mirror goes on the truck from the factory? I will investigate further in the future but I thought maybe someone on the internet could help me out? It would be so nice if all the wiring is there and I can just buy one with all the extra functions that I would like it to have. Thanks in advance.
