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.

I think you need to take test light check your System out your brake lights run with it off not wen power on are your lights dim your wires at rear truck It shouldn’t matter no power needed for brake lights They run off turn signal brake light you should have in wire colors yellow green brown I believe last wire Is black for ground take your tail light cover start. With power you should have test light see if it blinks Like it should they onlyminitue check do it at power box or always rember were do you live I’ll fix it easy My name is Dan iam in canyonville or
