Yes I have 12v to it!
What is your experience with this?
Just to be sure, when you say you have 12V to it, do you mean from your trailers battery or from your vehicle?
The breakaway is wired to pull power from the trailers battery (which is the only way it can get power if it breaks away from the tow vehicle). If for some reason, you have the trailers battery disconnected or removed, then the breakaway will not work.
