that's 3/6 in the forward half of the rear harness connector behind the kick panel that does have fire when pedal pressed but you connect the halves & no br lites as in no continuity from the connector to the rear when you connect them?
Correct. Although, it can't be a continuity issue in the connector itself because the blinkers work.

but from the batt directly to 3/6 in the rear half of the kick panel connector you're good?
Correct.

And w the kick panel connector connected and jumping fire upstream from there to the white wire at the rear half of the dangling TS connector no brake lites?
I have not jumpered up stream to the white wire (7) yet because I was already showing 12V there. But I think that's my next step.
Thinking about this again this morning, it's almost like I'm getting 12V but I'm not getting enough AMPS at the connector (3,6). I've been using a volt-meter for all this testing, not a test-light, so it's not obvious if the Amps are down when comparing the voltage I'm getting from the brakelights, compared to the blinkers (that work fine).

Your park lights have nothing to do with your signal and brake lights other than a common bulb but on the other filament. if your signal lights are working at the rear of the car your tail lights have ground , your wiring is not an issue on the brake light/signal wire as you have proven that already. You have two separate issues park lights brake lights They are different circuits going to the rear of the car . do you have park lights on the front ? I would give no credence to your wiring harness codes as your harness could have been altered. It should be very easy to confirm your park light circuitry by unplugging from your head light switch ...finding the hot wire and then jumping to the supposedly correct wire as the book says. If that doesn't work , go back to the trunk and unplug the tailights and jump in with a known 12vs. remember the park lights are the dull side of the bulb. Now your brake light,i suspects its the harness plug at the steering column providing you already proved that there is always 12v at the brake switch. there are not many more things it can be .....its not the bulbs , its not the wires going to the rear. so whats left? Power to the brake switch , steering column harness plug or the signal switch . nothing else to look for !

well hope thats the trouble, and yes you can have 12v on your meter but very very low amperage which is why stuff don't work. maybe some corrosion on that wire .
good luck
That was it. Corrosion on the terminal that the outbound side of the fuse plugged into. Hit it with a small wire wheel on a dremel, added a little solder to the connection and everything WORKS. Brakelights, parking lights, everything.
That was the FIRST THING that I checked when I was trying to diagnose the problem. I had no idea that my multi-meter could show 12V but the circuit itself was dead. Gar!!!!!! I always thought test lights were for dudes that didn't know how to use a meter. Joke's on me.
Worse - I had disassembled a lot of stuff downstream. I just finished re-installing my dash cluster after I realized I could not remount the headlight switch without pulling the cluster out.
Good news is I'm all good to go.
Thanks as always for everyone's help. And particularly the guys that said my multi-meter could lie, that I didn't pay attention to.....  Lesson learned.

I learn't sumpin today, I had no idea & always figured if the meter showed 12V then it was hot 
Well most times you have 12v showing on a meter, chances are you have a good lead. but sometimes as in Gus's case he had 12 v but not amperage . Something like lightning, billions of volts but very little amperage , if lightning had amperage on a decent ratio of the volts it would destroy everything in its path. just like bombing .
About a decade ago up here in newfoundland , an energy bust of some sort struck a community on Bell Island not far from where i live. It was a clear sunny day so I guess it wasn't lightning , but it dug trenches in the earth just like an excavator, blew up every electrical device around the area, blew the electrical meter right off the houses, killed pets and live stock. One little kid was riding his bike in the middle of it and luckly never got hurt but said there was balls of fire about as big as a beach ball going down the street slowly and about 4 ft off the ground.
Some people said it was the US testing its light beam gun or something. Military never siad much about it .Hmmmmmmm.
