Let's take it step by step. Do you want to replace the default body (picture above) with another body made by you, right ?
So, regarding to connections between parts, here the things are established by communicators... you know? IN PUT and OUT PUT. If the CIL(R)/(S) is well linked by the COL(R)/(S) then the connections are suitable. But pay attention at matching name... The matching name of an CIL(R)/(S) MUST BE the same for an COL(R)/(S).
CIL - communicator input left
CIR - communicator input right
CIS - communicator input single
COL - communicator output left
COR - communicator output right
COS - communicator output single
