SimMechanics: Properly connecting joint blocks and constraint blocks with bodies

Hello,

I am working on a model of the human body and am trying to get it in full kinematics mode. The problem I am having is connecting joint blocks and constraint blocks to the same bodies. I may not even be doing it correctly. I have not used constraint blocks before so I am new to this.

My question is:

How do I properly connect the constraints and joints together so that a kinematics mode is possible?

Thank you!
