Yes my 2004 aveo came pre wired in the body, not the doors, for the front doors for power locks, windows, and mirrors. It was not pre wired for the rear doors though, kind of odd but maybe thats a separate plug in harness? The body also already had the fuses and relays. But when I added after market power door locks I didn't use any of the pre included wiring, relays or fuses except the power door lock fuse to supply power to the after market power door lock controller.
