trans ?'s

I ordered a 4l80e swap crossmember for my trans from a member on here but I need to know which crossmember I have also Here's a picture of a the crossmember and the trans I just bought. I noticeded that this trans has a provision for one bolt on each side rather one through the middle. Is that the norm for this trans.

My other question is the my 4L60e had a round green plug but the 4L80e I got has a round blue wire connection.
