My stop lights do not work. Blinkers and tail lights do. I have a few wiring diagrams but they all show 2 wires going to my brake switch and I have 4 wires. One conector has an orange and white, the other a pink w/ black stripe and a blue. Orange and white run up into my insterment panel and the pink and blue run together till the pink connects to my fusebox and the blue wire exits. I took the switch out totay and now my blinkers do not work either

The orange wire should have 12 volts all the time. If it doesn't, check for voltage on the fuse. If it's there remove the fuse box and check for a corroded rivet where the wire connects. If you have the 12 volts it must show up on the white wire when you push the brake pedal. If it doesn't, the switch is bad.
