Damaged transmission harness

I am doing an AODE to manual swap, so i purchased a transmission harness but it came damaged. The part the juts off the main line, the circular connector the internal metal circle prongs are bent/twisted up. What is this circular connector for and how necessary is it?
 
depending on year model harness you have you will have either 2 or 4 connectors 1 vehicle speed sensor (square plug),1 backup lamp switch( round plug),96+ harness has 2 heated oxygen sensor plugs (round plug). i believe its the back up lamp switch plug thats bad on yours.
