66 dart electrical problems

Ok. Double checked the harness and steering column connections. All good. Started at the bulb sockets with a tester and worked my way backwards. Nothing at the sockets, the plugs, the bulkhead connector. I do have power to the light green in the TS switch which I believe feeds the park lights in front. But, no park lights. Activate the turn signal, no turn signal but I can hear the horn relay activate (I unplugged the horns). I guess I'll order a new TS switch and see what happens. Also, still no stop light. Checked the bulbs, running lights come on but not the brake lights. Gotta be the switch. Thanks all, I'll keep you posted!
