I want to add BLIND SPOT MONITORING MIRRORS to wifes' 17 Tahoe

What kind of a GM Truck site is this? This is the best advice it provides for this guy who wants to upgrade his side view mirrors to have blind spot monitoring? There must be a way to do this that is affordable from a donor junkyard vehicle with this option.

Define affordable.  If it was an option for the vehicle in question, the wiring and modules and such could be added and the person would then have to program the modules themselves.  A dealership will not do this, is not allowed to do this.  Said owner would need to purchase an MDI adapter along with GDS software and get a 2-year, $40 subscription to ACDelco's TDS system.

 

First thing to do is have a look here to see if it's an option for the vehicle in question:  https://tis2web.service.gm.com/tis2web

I stand corrected. I was ignorant of the fact that the sensor technology is not simply wholly encapsulated within the side view mirrors. (Perhaps others are also unaware that this is not a simple function of the mirrors alone and is much more complex) After a more thorough investigation, blind spot detection utilizes sensors (and electronics) located outside of the side view mirrors and the indicator light in the mirror is simply for driver feedback. Goshers offers (or offered) an aftermarket kit, but it appears that installing the sensors pointing in the exact correct location is critical. Brandmotion also offers a kit at $799.95 which in my opinion is a bit pricey. 
 

So bottom line is that this is not a simple mirror replacement bolt on thing. (I was naive!)  It’s much more complicated than that. I learned a lesson. Hopefully this will help others as well. Looks like the best approach is to buy a vehicle with this tech included from the factory or use a convex mirror add on if your side view mirrors don’t already have them. Sorry for the confusion on my part.
