Please be aware that I know NOTHING about what I'm asking, but the hub's Tacoma got crunched in the front end so he's adding a trailer hitch to his 2007 Vibe so he can work out of our lightweight Thule trailer, for a while.
Bought the hitch - probably overpaid, but whatever - and then tried to figure out wiring. I, of course, came here, and I think he's going to get one of these:

but I've seen some posts here that say that any wiring connections or taillight converters or whatever he gets have to be POWERED. I don't think this one is, but I've seen it recommended in a few different posts.
So - which is it? Is this item powered, or doesn't he need power, or does he actually need to buy something else?
