In my case (centipede cab with a florescent light), it just needed 110, so I just took a good extension cord, cut it open, and wired it up. I have a power strip that turns on the outlets when it senses current for the computer, so with the monitor, speakers, and marquee light controlled by that, it works great.
Of course, you would need to be careful doing this and if you don't know what you're doing with this kind of stuff then don't even try.
