Your tail lamps get voltage from headlamp switch. You can see the fuse, did you check the fuse? Also, use a test lite to check voltage on fuse circuit, hot all the time. At the rear lamps, brown wire is voltage for tail lamps and black is ground, use a test lite and check both. If turn signal works at the rear, ground is probably ok. All I can do is help you with testing.
