Thank you

The best place to find the correct answer would be your GM dealer or call one of the performance GM parts dealers and ask them.
The art is in how to phrase the question.
You have to ask them can a 2017 replacement engine be used in a 2015? And can a 2015 engine be used in a 2017?
And if so are there any changes to the sensors or harnesses?
A quick search tells me they are the same. The below site says the 12679879 part number fits 15s, 16s, and 17s.

But I would talk to them to confirm.
