In older houses the wiring may be way outta date, these older wires consist of only two wires(hot wire and neutral/ground wire). Today we use a three wire system(hot wire,neutral wire, and a ground wire) seperating the neutral and ground wire from being carried on the same wire.
 
 
If you installing a light fixture and hooking it up to the older 2 wire system, it is recommended to install a jumper wire from the grounding screw to the wire nut where the white(neutral) wires connect.
 
 
Where referenced below in the guide and diagram as being "the supply wire" refers to the wire suppling the electric to the light fixture. To prepare the wires for connecting them together strip the plastic down from the end of the wire half of an inch.
Light Fixture Wiring
Step1.
Connect the black(hot) wire from the supply wire to the black(hot) wire from the light, twist together and install a wing nut to cover the exposed ends.
Step2.
Connect the white(neutral) wire from the supply wire to the white(neutral) wire from the light, twist together and install a wing nut to cover the exposed ends.
Step3.
Install the bare copper(ground) wire to the grounding screw located on the mounting bracket for the light fixture.
Step4.
Mount the light fixture onto the mounting bracket and install fasteners.
Step5.
Turn on the light and enjoy.
