just like any other in the past except you have to unplug a timing connector befor setting it. leave it disconnected until you get the timing set. its located either under the carpet on the passengers side(just pull it down a little to see it), or under the big plastic cover under the hood on the passengers side. either way it will be a tan and black wire. the check engine light will come on just disconnect the battery when your done to reset your light.
