I am attempting to rewire a warrior my friend recently bought I have 3 different wiring harnesses. I found that one of the harnesses plugged into most of the controls went to crank on it and got nothing. Everything I can see is hooked up. But I have a mystery wire it is RED with a BLACK tracer and with the key on it is hot. I have searched all over trying to figure out what it is or where it goes and have come up with nothing. Any help would be great.
