I see the letter designation for the different color wires on the old connector harness but there is no letter designation on the new harness connector to know which is the black ground wire?

Use the old one and match it up with new to tell which letter is which.That's all you have to do use it as color key as well that's what I would do.

The new connector on the left is a different shape than the old connector so I don't know how to match them up Because they don't line up the same.
