Go to Youtube and look up JamesFreddys channel. He does autobody vids and his own personal project is a 72 Dart that he has done this swap to. You will need to search through a lot of videos to find the info you want but its all there. He has vids showing how he worked the tunnel to get the new tranny to fit and everything. I don't remember off hand if he made his own wire harness or bought one but the info for that is all there too. If you don't want to go back and watch a lot of vids he is a cool dude you can PM him there and I am sure he will tell you what ever you need to know.
Although I don't know if he is a member here but I do know he does read this site from time to time. So a lot of the info he used is prolly buried in this site somewhere.
