Question
I have a ls 400 and the the third brake light you know the one on the back deck inside the window ? anyway all the other brakes come on when depresing the the foot pedle I have checked the conector but there seems to be no power there can you tell where this ties into the harness ??

have looked on the net ?? so if you might have a diagram would love to see it ?  

Answer
Have you tested the bulb holder with a test meter as its the only way to see for sure if you have no power to the light unit.Do this before you try anything else as the unit may simply have a loose connection.I dont have a diagram for this but most of the Lexus have the wiring for this running into the trunk or under the rear shelf.You may have to remove the rear seat.
