Have a tail light problem on my 1960 GMC step side . I have power to the headlight switch but no tail or brake lights .The headlights work as they should . If I jump the red power in wire on the headlight switch to the black tail light wire the tail lights work . If the light switch is turned on or if I run a hot wire to the brake light switch the brake lights work. I have replaced the headlight switch but no difference . Can't figure this one out.

Thank for any help
