More electrical gremlins....

Turn the headlights on, today testing bulbs etc.... And the tail lights dont work, stop, turn, brake,reverse and tail, the rear corner markers work though
I checked and cleaned the ground in the back,
And i replaced the headlight switch when i restored all the guages (Questioning if its a bad one)

Last fall they worked. before i started the cluster re-do Any help with this would be awesome

The black wire that runs out back has juice, hense the rear side markers work, but the tails dont, i think its the same circuit. please correct me if im wrong.
The violet i believe is for the reverse lights
Green is for i believe the turn signals
And brown i think is for stop and tail.

im narrowing this down to a faulty new headlight switch, even though all te lights up front work...

UPDATE...
ive been messing with this all afternoon and im gettin aggrivated. im 90% sure from the kick panel back is fine.... the problem lies from there forward. im hopeing its just a faulty headlight switch.

also, the dash lights work fine and dimmer works correctly, headlights work, high beams work front turns work fornt markers work


i am lost as to why this is.... any help would be awesome thanks in advance
 
Sounds like a switch to me.
Also Stop and Turn share the same wires. Tails by themselves. Pull the connector behind the kick panel cover and see if you have power there.
 
All fixed. Took care of it. The connector at the kick panel was messed up, the pins were a mess.
Fixed that, and now one of the tail light sockets is junk, its all rusty, and the spring loaded contacts are stuck all the way down so the bulb doesnt stay in
