I went to the junkyard and got a dome light out of a 95+ ranger and put it in my 94. It turns on when I open the doors but how do I wire it so that the switch can turn it on also?

There's the diagram, maybe that'll give you a hand. If I read that right it looks like your maybe looking for a light green/yellow wire and a black/light blue one to wire it right. Top left of the image.
