My brake lights do not work, the other lights work fine. I have replaced the switch, I can use the power probe and make them work from the pedal switch (the wires from there back are fine). It seems like the pedal switch itself is not getting any power.

Hello, I'm Danny.

It sounds like you may have an open wire in the brake lamp switch circuit. Here is a tutorial showing how to test electrical wiring:

I've attached the brake system wiring diagram below. I've cut the picture into 3 pieces so you can view larger. Hope this helps and thanks for using 2CarPros.
