Everything is installed. I ended up forking over the money ($295 total) for the dealer to reprogram the BCM. I am sure if you had the right dealer you could get this done for less. But be prepared, for us 15/16 model year guys, the "tech line" does not want to give us activation codes for used equipment. You have to find the right person to talk to.
I have a complaint in with this dealer, not sure if it will go any further than that. It isn't totally their fault as I would imagine it is GM's stance on the use of used parts, just seem silly since the 2017 models are plug and play now :(
