tailgate brake lamp wirring?

[juzatheman]

Hi all,
i just noticed that my tailgate brake lamp does not work.

all the bulbs was burn out and i change all three bulbs, but still nothing.

there comes ground command to the bulbs when press the prke pedal,
but no pwr.

does anybody have a clue where the pwr. comes to the bulbs?

or have a wiring diagram for the lights?

i asume that the "extra" brake light is behind of the same fuse than normal brakelights or is it ??
