:Back-up lights

I started looking at the diagram. Now I'm crosseyed, part blind and have screwed-up lights.
I guell i'll have to crawl under the dash anllook for the hot wire. I didn't think about the wiper switch being a terminal. I was thinking it would come off the fuse box which has two sections, always hot (acc and run) and only with key on run only. Well at least I have colors. Maybe I can blow the digaram up so I can read it but I guess I have the info here.
I wonder if there was a TSB on some cars being hooked up wrong.
Thanks,
GEORGE!!
