Welcome I'm Chris aka Moose
Are all brake lights non operational, including the lower 2 and the upper one? Can you get the car out of park while running?

At the stop lamp switch back probe the connector so it can be tested while plugged in. Does the light blue wire have power when you press the brake pedal?
If there is power then its a wire break in the harness we need to find. There is a connector under the left front seat where this wire breaks up to the lower 2 lamps and the upper one, next we need to check there for power with the brake applied.
No, at the stop lamp switch.
Black on the chassis so its grounded will be fine, like the brake pedal mount or seat bolt. There are no ground wires to the stop lamp switch. If your sure you can fully depress the plunger then yes you can do it while off.
Does the orange wire from fuse 9 have power all the time regardless of the brake pedal up or down or even plugged in?
Orange is the power, when you press the brakes, the orange wire internal in the switch powers the light blue wire. You can ohm test across these 2 pins, you should get a closed circuit with the pedal pressed. You can unplug the switch and jump a paper clip across these wires and the brake lights should work.
I cannot tell by bulb number, that information is not in the repair guides. There should be 2 bulbs in each rear combination lamp. The turn signal bulb has a power and ground pin. The park lamp and stop lamp bulbs are the same and have 3 prongs. park lamp power, stop lamp power, and ground. Would a wire diagram help?
Use the link below.
We are back to the testing at the brake switch where you tested the light blue wire, this wire must have power when the brakes are being applied.
