I'm not sure how to wire this, but my anchor has 2 wires coming off of it. I'm trying to put it on a on off on switch to go up and down. Here's where I run into problems. One wire to a positive, and ground the other one, the anchor motor pulls the rope. I can't figure out how to reverse it? I tried to switch positive and negative and that did nothing. Is there something that I am missing here? Any help is appreciated!<br />-Gerry
