Best / easiest way to remove old electrical connectors?
Use a pry bar through the eye of the anchor. You are correct, rotating top left will bring them out. Alternatively, an adjustable wrench over both sides of the eye works very well. Turn it right out, don't cut it off, because it's much easier to caulk shut a hole or put new flashing over it if there's no stub sticking out. There are some eye bolts that go through the wood and have a nut on the inside. In those cases, you can remove some soffit and put a wrench on the nut inside. Don't get hit on the head when it comes out, and don't stand on the top step of a ladder.
