One goes on the back of watermanifold. you might have to buy an original outlet that screws into the manifold. the other one goes on a fipe that comes from the waterpump if i remember correctly. you might have to buy the pipe accessories too.
found both plugs .... the water manifold I figured was 1 but I wasn't sure of the water pump fitting after giving the front of the engine a good bath there it was!
