Tail lights we'll call park lamps. These and the tag lamp are all on brown wire, same as front park lamps, and that park lamp fuse. Turn signals are a green and a yellow for left and right and on a different fuse. Brake lamps do use those same green and yellow wires but that power comes from a different fuse. The turn signal switch in the steering column selects which green/yellow wire(s) is connected to which circuit and fuse.
Then reverse lamps use purple wires. Aint no way just 1 blown fuse disables all the rear lamps. A wrong type bulb, faulty bulb socket, other short circuit in rear lamps could blow multiple fuses.
