converting foot pump to electric windshield washer

well at this point i am just looking at what is involved. i guess it is not so much as to what i gain kinda thing as to just having something i am more used to. if i do it, it will be one of those things that i will do as i get to it . i have acess to a few of the parts now so it is not out of the question. i was just wondering what all i needed to do it.
