    Thank you for posting! I don’t quite understand what you mean when you say “chop the black wires” If that means “cut them”, I don’t think you should be cutting any wires before you try to figure out which wire goes where. But before you do that, you probably ought to disengage the battery first, so you don’t accidentally short something out.
