Connecting array attributes in Maya Python API 2.0

Question

How to connect 2 array attributes using Maya Python API 2.0? e.g:

joint1.worldMatrix[0] >> skinCluster1.matrix[0]

I can find plugs but how to connect them?

import maya.api.OpenMaya as om

node = 'skinCluster1'
attr = 'matrix'
index = 0
def get_plug(node=None, attr=None,index=0):
    m_selection_list = om.MSelectionList()
    m_selection_list.add(node)
    dependency_node_object =       m_selection_list.getDependNode(0)
    dp_node = om.MFnDependencyNode(dependency_node_object)
    attr_plug = dp_node.findPlug(attr, 0)

Answering my own question :

om.MPlug.elementByLogicalIndex(index)

this will return plug with indexed attribute.

MDGMoifier() do have connect function. One should pass source and destination plugs and then use doIi() function to connect. I think this answers the question.

This does answer the question how to find an attribute in an array attribute, but it does not answer the question how to connect them.

Sorry I edited my post. MDGMoifier() does this function
