JB4 BCM install on 650i gran coupe xdrive

[DownwiththeQs]

I have a 2014 650I gran coupe Xdrive. had the JB4 installed, a couple months back, and am enjoying it. Just found out yesterday I can connect the BCM (Boost Control Module) and run higher maps and get more power. I've searched everywhere how to install them. asked Terry at burger motorsports, he recommended looking at the S63TU install guide and it would be in there. However, the S63TU is a little different so directions aren't direct for my car. Does anyone know, or have a video they can post of how to install the BCM? Please keep your answers relevant to the question in this post.
