Dash lights not working on 73 Duster

It should be fairly straight forward to jumper power from the main power lead on the switch to the dash light terminal for testing.
Just tried the other switch and still not working, lights are fine still but one of the rear lights is slightly brighter than the other, looking at the rear wiring on the drivers side, green twisted to a black and other wires going to a block connector on the other side which i can't find in the trunk and it's hard to see what colour they are.
