Found what was the problem of my tail lights....on the trunk found a little box called fail lamp...it matched the colors to the tail lights...then i tested all with a power probe and walla found that the little box called fail lamp was causing the trouble on not turning on the tailights....

Im having a similar problem. Where exactly is that box in the trunk. And your car is a sc400/300 right?

Sc400 the box located left side of your trunk inside panel need to remove the panel carpet therefore follow the wiring of yor tail lamps you will see it quick
