Transplant question

I have a 68 cuda vert. I got it without engine or tranny. It previously had a 225 in it. I picked up a 225 from a 68 Dodge Dart. Anyone know what I am going to run into when I decide to install? I already noticed the tranny on the "new" motor has a three prong plug and the cuda has no female end that I can find. Also appears I am goint to need trans linkage. Any ides on that?
Thanks
