98 xj console

I have a 98 xj se. I want to add the overhead console. what do I need to do that? obvisouly the console. but do I need the wiring harnesses? computer? I need the temp sensor too. Will it just hook up to my xj? Where does the harness hook into?

Can this be done, or is it more trouble than its worth? My other jeep I put a sun roof in, I figure If I put a console ini, I won't be compelled to cut a big hole in the roof of my jeep, those damn metal shaving sure are itchy, next time I'll cover the seats better.
