Wire a toggle into the ignition and label it winch or back up lights. If thieves think it goes to something else, they won't think of it. You mark it as a light of some type, no thief is gonna touch it. They don't want to light up the area before it's even started, or so they think that would happen.
If you label it as a light, for extra trickery wire it so it actually does run the light. Just make it a light that you know is going to be on full time.
