A diagram won't help if you aren't using a voltmeter and don't know which wires are for what. Call an electrician before you cause damage or death. If you insist on doing the weekend hobby that kills, look for the diagram on the back of the panel where the wires are or call the manufacturer to tell you where a diagram is. I have serious doubts about people wiring something when they don't know they need to ask for wiring diagrams for a particular make and model; but believe they are all the same.
