The BCM connector wire colors on your 2015 GMC Terrain could vary during production. I recommend using a circuit tester such as # PTW2993 on the wire in the number 11 terminal to determine its function. I included a diagram for you to view.

Another method is to use a fuse tap like # F2526 on the CHMSL (center high mounted stop lamp) fuse in the fuse box. The lid should have a description of which fuse location is needed.

I included a couple informative articles for you too.
