Brake Light Switch or Turn Signal Switch?

1972 Dart Swinger. The car has been converted to a 440 with 727 ratchet shift

Having trouble with brake lights, specifically none. I took the rear light assemblies out and cleaned them thoroughly but have not yet reinstalled.

I am using a low voltage circuit tester and verify that the 20A fuse is hot for the brake lights.

I probed both wires to the brake switch and am showing that neither is hot, with or without the brake pedal depressed.

I took apart the steering column to the TS switch to see if I could follow some of the test procedures on other forums but I've confused myself a bit now.

I get no flashing from the blinkers, when I engage either side.

I get no emergency flashers when the switch is on. If I have either blinker and the emergency flashers engaged, I get blinking flashers (remember I only have the front lights in right now, was not getting power to the connector in the rear when I removed them).

With the Emergency switch off and the L blinker on I only show two wires as hot, R and G
With the Emergency switch off and the R blinker on I only show two wires as hot, R and br

With the Emergency switch on and the L Blinker I show hot at (R,Y,W,P,G,br)
With the Emergency switch on and the R Blinker I show hot at (R,Y,W,br,G,P)

Do not show hot anywhere with key off and all neutral.

Can anyone send me in the right direction as to what to test next? I'm certainly not an electrically savvy guy or I would have been able to dissect the loads of information you all have already provided. Thank you in advance.
