I wish I knew, I'm just regurgitating what I've read on other forums. I myself figured if I was going to use it I'd just buy a wireless camera system. Why would I need a wire? I think they just threw it in so they could slap another sticker on the trailer. I've never seen someone yet post up actually using that wire. Just like the pre wired for solar claim that is really just that small little connection right next to battery for a tiny battery charging panel. Anyone going solar knows you have to run all new heavier gauge wire and complete system, but yet again, another sticker they got to slap on trailer.
