However, the wiring diagram shows it doesn't connect to anything in the panel, so it should just pass through in the wiring bundle up to the headlight switch correct? My next step tonight will be to trace the blue wire from the headlight switch to the dimmer switch.

The blue wire simply "passes through" the bundle of wires at the fuse panel/bulkhead connector.. And just for the record -- there are no fuses in the headlight wiring.. The headlights and their associated wiring are protected by a circuit breaker built into the headlight switch..
Before you start tearing the wiring bundle apart tracing the blue wire between the dimmer switch and headlight switch, here's a more simple method of checking.. Unplug the harness from the headlight switch and the dimmer switch.. On the headlight plug, check for voltage on the large red wire.. Should be 12 volts... If you don't have voltage there, you probably have a bad connection where it passes through the bulkhead connector. .Or somewhere along it's length as it makes it way through the Harness starting at the battery positive terminal..
If you do have voltage on the red wire, put a jumper between it and the blue wire.. You should now have voltage at the dimmer switch plug.. If voltage is now on the blue wire, connect the plug to the dimmer switch and check for high and low beams.. If voltage isn't present, the blue wire is broken somewhere between the two switches.. Repair as needed.
You stated you have replaced the headlight switch??? Be sure it's a good one and be sure the terminals in the plug fit very tight on the switch
If you need a wiring diagram It's available in "wiring diagrams" thread located in the ELECTRICAL forum.. Also, a digital multi-meter and/or 12v test light will be very useful..
