So im wanting to 2 S1's and i know that they usually use 450-500w, and i dont want to buy 2 PSU's so i was wandering if there was a way to wire a plug from the S1 so i can plug it into my wall? Sorry if its a dumb question, im just curious

Ignoring the terrible idea of you burning down your house.
Why not buy 1 PSU to run both of the miners. I did that when I bought my first s5's, I picked up a PSU and ran 3 of them off it.
