Ignition switch is located above brake pedal on column. It has long flat electrical connector to it. If by ignition switch you mean the key tumbler: Remove steering wheel. Remove lock plate. Remove Turn signal switch. Remove screw retaining ignition. There should be a code stamped on the ignition. If the ignition is still good a locksmith can cut the key from the code. Might be cheaper to slap a new one if you have already got that far though.
First, remove the lower dashboard panel in order to get at the switch. There are four Philips screws and one bolt that secures this panel. Then remove the two nuts and three bolts securing the steering column to the dash frame. This makes it easy to get at the switch. Remove the cover around the ignition switch. The front part is the key and lock tumbler, and the bottom is the electrical switch part that is not disturbed by this process. Take care not to pull the wires in the wire harness to the switch. Remove the key sensor switch from the housing that holds the tumbler and switch mechanism. Remove the screw that holds the ignition switch body. Remove the electrical harness part from the back of the switch. Then, insert the key and turn slightly. Release the pin under the tumbler casing and pull out the cylinder.
