there is a bolt on the back of the manifold that you have to take off. it is a 12 and it goes straight back into the manifold. if you look at the manifold it is on the middle right side. Feel around and you will find it. also there are two bolts that are holding down a bracket that you must take out also. they are on the driver side of the manifold. they hold a bracket that holds two steel lines. they also go back into the manifold. look close and you will see them.
