To connect attributes using connection lines

1. Click the connection line.
2. Drag one end of the connection line (it turns white when you point to it) to the material to which you want to connect the node, then select an attribute from the Connect Input menu.

   

   Maya makes a new connection, a new line and new node displays, and the material updates with the new connections.
