brake light switch on 2002 c230


I cannot get my 2002 c230 to start, the shifter will not move from park and when I turn the key nothing happens. I googled this and there were indications that the brake light switch could cause this. the test was that when moving the shift lever (I found how to manually do this) the movement should show on the instrument cluster. it did not show so I bought a new brake light switch. I watched several utube videos on changing the switch and removed the panel to access the switch. I contorted myself to get under the dashboard and see the brake pedal. I could not find a sswitch or the wires that the switch would plug into. all the wires under the dash were accounted for.
