Open the cars hood and look for a usually black cap about 6 inch's in diameter,with 6 wires 1/4 inch in diameter coming out of it.The wires will go to the spark plugs the wires may or may not have numbers on them.Also the distributor will have a small electrical connector on the side of it.4 screws are in cap and are used to hold it down.Or go to auto zone .com and follow their directions and they will show you a picture of it.I hope this helps,please click accept.Thanks
