You can get it pre-wired or non wired. If you get the one you have to wire then you'll need a $1 ext. cord and the ability to read a diagram. My sister did my first one, but I did the 2nd one without a problem.

Here is the link to the Pre-Wired, it'll run about $80
Pre-wired Ranco

and the link to the unwired Ranco, about $60
