Did this last summer
I wrote up such details as I could remember in a blog post, linked with this post. It's not as informative as I would have liked and I don't have time at the moment to fill in most of the blanks, even if my memory would allow it, but I think it answers some of your questions about the placement of the computer and rudder sensor. Also has some pictures so you can get an idea what it looks like.If you search these forums you'll find even better information--not long after we installed ours, there were several posts that were made which showed some much better ways to do things, particularly regarding the rudder sensor install, which was the biggest pain in the ass of the whole project.Good luck!
