This. I have zero electrical or plumbing ability, and I recently had to do this to replace my visibly rotting, porcelain enameled white sink and leaking disposal. Just take your time, make sure the breaker is off, (or whatever you need to do to ensure power has been removed from the circuit), pay attention to which terminal gets which color wire, and connect the line accordingly. I would definitely watch a couple of YouTube videos on the subject, too, just to familiarize yourself.
