If you open the Roli Example Project in ARC, it has assembly instructions in the project. You should also take hte Roli tutorials here: https://synthiam.com/Tutorials/Course/3 which includes a tutorial on assembly, including all of the wire connections.

The red and black are ground and power to the H-bridge and go to port 0, but like I said, follow the tutorials so you get everything correct.
