Yes, you could use the Pollak 2-Pole Trailer Wiring Connector and a 4 gauge wire to power a small winch as long as the wire gauge for the winch is not thicker than 4 gauge. Since the winch is small, it likely uses 8 or 10 gauge wire, so you should be fine.

I have attached a help article that explains different methods for wiring an electric winch for you to check out.
