Try under the dash near the glove box.
I don't know how to change the ignition switch but I have some advice. Don't screw with the ignition switch, buy the whole steering column. It will be cheaper and easier to change.
The 1997 Pontiac Trans Am 5.7 liter engine oil pressure switch can be found on top of the engine. The oil pressure switch will be near the intake manifold.
On top of the steering column. ////////take a look on the transmission
Under the cap, inside the distributor, it is easy to change with the distributor off the car, a pain to get to with it on the car.

there is no such switch on this car. sorry but mainly fords have it.
Have you checked the ignition switch on the column . I had to replace the one in my 1977 Trans Am.
The Ignition Control Module (ICM) is located directly above the coil. If you remove the 2 bolts holding the coil on and then romove the coil mounting plate from the car you will see a small rectangular module with wires plugged into it. This is the ICM.
Center of the dash.
Gas Tank
no such thing as a trans switch
