Do it the easy way. Go to the box and turn off the power to the whole house, no chances of an accident. After that, electric repairs are fairly simple and straight forward. It is "usually" white to white, black to black, green to green, red to red, blue to blue, etc. You will probably have a copper colored wire that does not have a mate to match up to, but there should be a little black or copper screw to attach it to. There should be picture instructions on the box. Shove everything (don't crimp the wires but they can be bent) back into the whole, screw on the cover plate. TA-DA done! Don't forget to go back out and turn the power back on at the box. While you are thinking about electricity, if you have another person to help. Mark inside the box, which breaker goes to which room in the house and/or major appliance if that has not been done.
