Remove cables from transmission

[JMO]

Could someone tell me how to remove the four connectors on the side of the transmission? The wires are coming from the engine bay. There is a large white circular one, and three smaller ones.

Cheers.

EDIT: Or if someone knows how to remove the lower half of the BBM. The small black bow that has a bunch of wires under it and a bolt on top doesn't want to slip through the gap between the runners.
