I believe I installed the Brake Light Switch properly; however when I touch the brake pedal I get no brake lights at all. I still can't get the shifter out of park also. I got a spark when I tried to splice together the wires for the new switch I installed; so tomorrow I intend to check my fuses. Maybe I shorted something out because I did not disconnect the (-) battery terminal before I started to splice those wires. I hope I'm not staring at a major repair cost here. Can't afford it right now. Thanks all.

You shorted the "stop" fuse.
