05 Sunfire Base power lock installation

[Hokaido]

I am looking for assistance on whether or not the 2005 Pontiac Sunfire Base has the wiring required for installing power locks.

If so, how difficult is it to install power locks? I'm looking into getting a keyless entry system, but am unsure whether or not installing power locks is worth my time.

Thanks for any replies.

open the door panel and see if the wire harness coming into the door has unused plugs.
