I need you to identify what you have there before giving any more advice, I can't identify it. Don't know what you are hooking up. What does the switch do? What is the plug for? Need more information. As far as the wiring goes, the red wire is the positive (+) and black wire is the negative (-). Maybe there is someone else that knows what it is and can help, I'll bow out for now until more info is available. Sorry, I don't want you to screw something up due to incomplete background info.
