69 Dart short

Back from vacation and back at it. Have made some progress.
Hooked up the test light to the fuse box. Great idea
Pulled the light switch out so I can look at it.
With the left kick harness disco'd, I get dash lights and RF running light.
My left dash blinker light is on.
If I disco the LF running light, the left dash blinker goes out. Neither blows a fuse.
With the LF disco'd and the kick harness reconnected, the test light gets bright(blow fuse) I loose dash lights, the left dash blinker goes on, and the left rear 1157 is on but very very dim.
Pulled seats and traced wires. Don't see anything obvious.
The journey continues.
