No working tail lights...63 Dart

On the older cars, park and tail come off different switch contacts in the headlight switch.

Tail lights go through the kick panel connector and to the rear. A good easy place to access is right in the kick panel connector, see if you have power there. If not, go right up to the headlight switch. Could be a bad terminal in the HL switch connector, or bad switch, or bad TL fuse Anything else "not work?"
