Thought I explained it Best I could. But for you I'll try again. Many, Meaning NOT all, Brake controlers will be destroyed IF you pull the breakaway cable out while the 7 pin / cord is conneced. Why? Could be it creates a short of some kind. Could be it shocks the controler. Could be the way some are wired in. I'm not sure. I just know it can happen. Seen it.
Now if you want to find out if it will fry yours. Hook up, and pull it out. Me. Not a chance I want to take. There are a lot of things I don't know how they work. But I know they do. Example. I don't know how 2 little wires carry all this internet stuff. But they do.
