Dash Lights Not Working

I'm banging my head against the wall here and hoping for some help.
NOT WORKING
WORKING
Using a test light with key switched to acc., I'm showing ground on both the + and - connections at each knob lamp (these are the rectangular night lights above each knob). I'm assuming that with the lamp connected to both the + and - wires, it would show ground on both terminals when there is no power.
With the battery disconnected and the + wire removed from the knob lamp, I show continuity to fuse.
I installed a new headlight switch (not mounted to dash - just hanging below) with no change. I did rotate the switch to make sure I wasn't dimmed down. I was told headlight switch did not need to be mounted to dash for ground in order for dash lights to work.
I've now ordered a PowerProbe III to inject power to various locations, but until it gets here I'd like to know if there is anything else I can check.
I was looking at the above Painless diagram and it shows an inline fuse for the dash lights. Does the OEM harness use an inline fuse and, if so, where is it located? That could be my problem.
The headlight switch connector was melted when I took it off. I've ordered a new one. The wires and all of the terminal ends looked fine. I plan on simply reinstalling them into the new connector shell.
