I have power at the fuse box but none @ pedal relay switch or @ rear lights , does anyone have a wiring diagram for brake lights ? mine is a 2006

 

are you saying you are getting 12v at the brake light switch located at the pedal?

 

no power at pedal switch ?

 

Two quick points. If it is a 2006, it is under warranty so if the dealer is near you, have them deal with it. The second (sorry if you already know this, I didn't and got "busted" by it during an inspection of the car), the brake lights only work with the ignition on.
