On the front on each side of the engine are the distribtor caps. The four wires from each of these caps go to the spark plugs, follow'm.

 

There located deep down in your valve covers. Get yourself a long socket extension but first you have to remove the black plastic covers on your valve covers to see them. Right where your oil filler cap is. Obviously 4 on each side.

Good Luck.
