Replace PixHawk with BB Blue


I am relatively new to the RC world so please forgive stupid questions. I am replacing the PixHawk APM on a plane I bought with a BB Blue loaded with Ardupilot.

I would like to keep whatever hardware already installed if possible. All the GPS and telemetry stuff seems to be OK but I cannot see a way to connect the 3DR Power Module to the Bone. Has anyone done this kind of conversion and how would I do the PM integration if possible?
